7	Future directions	Guide, Mozilla, SpiderMonkey
		This article documents future directions in functionality, design, and coding practices for SpiderMonkey. It can be read as something like an "ideal future state" for the engine. That means the code as it is today won't match this document, and that's OK. Whenever practical, new code and changes should move code closer to the ideal future. And of course, the idea of the future is always evolving in time as things change and we learn more.

32	JS::CloneFunctionObject	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		JS::CloneFunctionObject creates a new function object from funobj. The new object has the same code and argument list as funobj. If scopeChain is supplied, it uses scopeChain as its enclosing scope. If scopeChain is omitted, it creates a new function object in cx's global. This can be helpful if funobj is an extant function that you wish to use as if it were enclosed by a newly-created global object.
33	JS::Compile	JSAPI Reference, Reference, Référence(2), SpiderMonkey

		JS::NewFunctionFromSpec creates a new function based on the given JSFunctionSpec, *fs. id is the result of a successful call to PropertySpecNameToPermanentId(cx, fs->name, &id).
56	JS::NullHandleValue	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		JS::NullHandleValue is a JS::HandleValue constant that represents the JavaScript value null.
57	JS::NullValue	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		JS::NullValue creates a JS::Value that represents the JavaScript value null.
58	JS::NumberValue	JSAPI Reference, Reference, Référence(2), SpiderMonkey

62	JS::PersistentRooted	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		Here, ptr represents the private member of JS::PersistentRooted<T>, typed with T.
63	JS::PropertySpecNameEqualsId	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		JS::PropertySpecNameEqualsId determines if the given JSPropertySpec::name or JSFunctionSpec::name value equals the given jsid, and returns true if so.
64	JS::PropertySpecNameIsSymbol	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		JS::PropertySpecNameIsSymbol determines if the given JSPropertySpec::name or JSFunctionSpec::name value is actually a symbol code and not a string, and returns true if so.
65	JS::PropertySpecNameToPermanentId	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		JS::PropertySpecNameToPermanentId creates a jsid that does not need to be marked for GC from JSPropertySpec::name or JSFunctionSpec::name. The resulting jsid, on success, is either an interned string or a well-known symbol; either way it is immune to GC so there is no need to visit *idp during GC marking..
66	JS::ProtoKeyToId	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		JS::ProtoKeyToId converts a specified JS prototype key key, to a JS ID. JS::ProtoKeyToId stores a jsid to *idp.
67	JS::Remove*Root	JSAPI Reference, Obsolete, Reference, Référence(2), SpiderMonkey
		JS::Remove*Root removes the variable that rp points to from the garbage collector's root set.
68	JS::Rooted	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		Here, ptr represents the private member of JS::Rooted<T>, typed with T.
69	JS::SetLargeAllocationFailureCallback	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		If a large allocation fails when calling pod_{calloc,realloc}CanGC, the JS engine may call the large-allocation- failure callback, if set, to allow the embedding to flush caches, possibly perform shrinking GCs, etc. to make some room. The allocation will then be retried (and may still fail.)
70	JS::SetOutOfMemoryCallback	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		Unlike the error reporter, which is only called if the exception for an OOM bubbles up and is not caught, the JS::OutOfMemoryCallback is called immediately at the OOM site to allow the embedding to capture the current state of heap allocation before anything is freed. If the large-allocation-failure callback is called at all (not all allocation sites call the large-allocation-failure callback on failure), it is called before the out-of-memory callback; the out-of-memory callback is only called if the allocation still fails after the large-allocation-failure callback has returned.
71	JS::SourceBufferHolder	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		JS::SourceBufferHolder is the container class for passing in script source buffers to the JS engine. This not only groups the buffer and length values, it also provides a way to optionally pass ownership of the buffer to the JS engine without copying. Rules for use:
72	JS::StringValue	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		JS::StringValue converts a given JSString to JS::Value. The conversion always succeeds.
73	JS::SymbolValue	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		JS::SymbolValue converts a given JS::Symbol to JS::Value. The conversion always succeeds.
74	JS::ToBoolean	JSAPI Reference, SpiderMonkey
		JS::ToBoolean converts a JavaScript value to a boolean. It implements the ToBoolean operation described in ECMA 262 §7.1.2.This function can not fail and the return value is always the boolean conversion of the argument.
75	JS::ToInt32	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		JS::ToInt32 converts a JavaScript value to a signed 32bit integer. It implements the ToInt32 operator described in ECMA 262-3 §9.5.
76	JS::ToInt64	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		JS::ToInt64 converts a JavaScript value to a signed 64bit integer.
77	JS::ToNumber	JSAPI Reference, SpiderMonkey

88	JSAutoByteString	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		JSAutoByteString takes the ownership of string and frees it in destructor.
89	JSAutoCompartment	JSAPI Reference, SpiderMonkey
		No summary!
90	JSBool	JSAPI Reference, Obsolete, SpiderMonkey
		No summary!
91	JSCheckAccessOp	JSAPI Reference, Obsolete, Reference, Référence(2), SpiderMonkey
		Check whether obj[id] may be accessed per mode, returning JS_FALSE on error/exception, JS_TRUE on success with obj[id]'s stored value in *vp. As for JSPropertyOp, id is either a string or an int jsval.
92	JSClass	JSAPI Reference, SpiderMonkey
		Use JSClass to define a custom class of JavaScript objects. A JSClass has a name, flags, and several callback functions for advanced customization of object behavior.
93	JSClass.call	JSAPI Reference, SpiderMonkey
		Note that when a custom object is called, a this argument is calculated for it just as if it were a function. That is, the obj argument received by the JSNative is the this argument, not the custom object that was called!
94	JSClass.flags	JSAPI Reference, SpiderMonkey
		The flags field is of type uint32_t. Its value is the logical OR of zero or more of the following constants:
95	JSConstDoubleSpec	JSAPI Reference, SpiderMonkey
		JSConstDoubleSpecs is used to define a set of double values that are assigned as properties to an object using JS_DefineConstDoubles.
96	JSConvertOp	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		JSConvertOp callback specifies conversion behavior for objects having this class, implementing the ECMAScript [[DefaultValue]] behavior for them. On success it must return a primitive value in *vp.
97	JSDeletePropertyOp	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		JSDeletePropertyOp callback is a hook that applications may install to be called at some point during property access. A JSDeletePropertyOp may be installed on a JSClass to hook property deletes.
98	JSEnumerateOp	JSAPI Reference, SpiderMonkey
		JSEnumerateOp is called just before an object is enumerated (via a for...in statement, an array comprehension, or a call to JS_Enumerate). It should define any remaining lazy properties that should be enumerable but are not yet defined in obj. This hook does not implement iteration: once the properties are defined, the JavaScript engine can enumerate them.
99	JSErrorFormatString	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		JSErrorFormatString is a struct to represent error message and type, returned by JS_ReportErrorNumber function.
100	JSErrorReport	JSAPI Reference, SpiderMonkey
		JSErrorReport describes a single error that occurs in the execution of script.
101	JSExceptionState	JSAPI Reference, SpiderMonkey
		A JSExceptionState object is returned by the JS_SaveExceptionState function, and is passed to functions JS_RestoreExceptionState and JS_DropExceptionState.
102	JSExnType	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		These types are part of a JSErrorFormatString structure. They define which error to throw in case of a runtime error. JSEXN_NONE marks an unthrowable error.
103	JSExtendedClass	JSAPI Reference, Obsolete, SpiderMonkey
		To implement a custom class that uses any of the JSExtendedClass callbacks:
104	JSExtendedClass.outerObject	JSAPI Reference, Obsolete, SpiderMonkey
		See split objects.
105	JSExtendedClass.wrappedObject	JSAPI Reference, Obsolete, SpiderMonkey
		If a class has the JSCLASS_IS_EXTENDED bit set in its JSClass.flags and has a non-null JSExtendedClass.wrappedObject, then objects of that class may be wrappers. In a few cases the JavaScript engine will pretend the wrapper isn't there, instead operating on the object it wraps. In these cases the engine calls the JSExtendedClass.wrappedObject callback to get the wrapped object. Most classes do not implement wrappedObject.
106	JSFUN_BOUND_METHOD	JSAPI Reference, Obsolete, SpiderMonkey
		This macro exists only for backward compatibility with existing applications. Its use is deprecated. Future versions of the JavaScript engine may not support or recognize this macro.
107	JSFUN_GLOBAL_PARENT	JSAPI Reference, Obsolete, SpiderMonkey
		No summary!
108	JSFastNative	JSAPI Reference, Obsolete, SpiderMonkey
		No summary!
109	JSFinalizeOp	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		The JSFinalizeOp is analogous to Java finalizers or C++ destructors. The garbage collector calls this callback for each object it collects. The finalizer's job is to clean up any resources allocated by the instance which wouldn't normally be cleaned up by the garbage collector (private data stored in the object by the application, file handles, etc.)
110	JSFreeOp	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		Various finalization API takes not JSContext * but rather either JSFreeOp structure or its library-private counterpart FreeOp. These structures wrap parameters that are passed to the finalizers removing most of explicit dependencies on JSContext in the finalization code.
111	JSFunction	API, Guide, JSAPI, NeedsContent, SpiderMonkey
		JSFunction is a type in the JSAPI. The APIs JS_NewFunction, JS_DefineFunction, JS_CompileFunction, and their Unicode equivalents return values of type JSFunction *.
112	JSFunctionSpec	JSAPI Reference, SpiderMonkey
		JSFunctionSpec defines the attributes for a single JS function to associate with an object. An application typically has an array of JSFunctionSpec to define all the functions for an object and calls JS_DefineFunctions or JS_InitClass to create the functions and assign them to an object.
113	JSGetObjectOps	JSAPI Reference, Obsolete, SpiderMonkey
		JSObjectOps is used by JS_NewObject's internals to discover the set of high-level object operations to use for new objects of the given class. All native objects have a JSClass, which is stored as a private (int-tagged) pointer in object slots. In contrast, all native and host objects have a JSObjectMap at obj->map, which may be shared among a number of objects, and which contains the JSObjectOps *ops pointer used to dispatch object operations from API calls.
114	JSHasInstanceOp	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		JSHasInstanceOp is called to check whether v is an instance of obj. Return false on error or exception, true on success with true in *bp if v is an instance of obj, false in *bp otherwise.
115	JSID_EMPTY	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		JSID_EMPTY is an internal jsid value which is used in type inference code.
116	JSID_IS_EMPTY	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		JSID_IS_EMPTY tests whether a specified JS ID, id, is JSID_EMPTY.
117	JSID_IS_GCTHING	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		JSID_IS_GCTHING tests whether a specified JS ID, id, is a GC thing, and returns true if it's a GC thing.
118	JSID_IS_INT	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		JSID_IS_INT tests whether a specified JS ID, id, is an integer, and returns true if it's an integer.
119	JSID_IS_STRING	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		JSID_IS_STRING tests whether a specified JS ID, id, is a string, and returns true if it's a string.
120	JSID_IS_SYMBOL	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		JSID_IS_SYMBOL tests whether a specified JS ID, id, is a JS Symbol, and returns true if it's a JS Symbol.
121	JSID_IS_VOID	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		JSID_IS_VOID tests whether a specified JS ID, id, is JSID_VOID.
122	JSID_IS_ZERO	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		JSID_IS_ZERO tests whether a specified JS ID, id, is zero (0 in its integer representation).
123	JSID_VOID	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		JSID_VOID does not occur in JS scripts but may be used to indicate the absence of a valid jsid. A void jsid is not a valid id and only arises as an exceptional API return value, such as in JS_NextProperty. Embeddings must not pass JSID_VOID into JSAPI entry points expecting a jsid and do not need to handle JSID_VOID in hooks receiving a jsid except when explicitly noted in the API contract.
124	JSIdArray	JSAPI Reference, SpiderMonkey
		JSIdArray is used to hold IDs for enumerated properties associated with an object.
125	JSIteratorOp	JSAPI Reference, Obsolete, Reference, Référence(2), SpiderMonkey
		The JavaScript engine calls the JSExtendedClass.iteratorObject callback to create an iterator object for a given object. The callback should return an iterator object or NULL if an error or exception occurred on cx.
126	JSMarkOp	JSAPI Reference, Obsolete, Reference, Référence(2), SpiderMonkey
		Call JS_MarkGCThing for each GC thing directly reachable from obj. Use JSVAL_IS_GCTHING to check whether a value needs to be marked and JSVAL_TO_GCTHING to convert the jsval to a pointer.
127	JSNative	JSAPI Reference, SpiderMonkey
		JSNative is the type of native implementations of JavaScript functions.  Full documentation of how to define a JSNative (or a JSFastNative, the equivalent typedef which preceded it) is available in the API header "js/CallArgs.h" Added in SpiderMonkey 24.  This header is new, but the semantics it describes are applicable to all recent SpiderMonkey releases.  The preferred way to implement a function is to use the JS::CallArgs structure defined there; the macros providing equivalent functionality are deprecated.
128	JSNewEnumerateOp	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		From SpiderMonkey 38, JSNewEnumerateOp is the type of ObjectOps::enumerate. This callback overrides a portion of SpiderMonkey's default [[Enumerate]] internal method. When an ordinary object is enumerated, that object and each object on its prototype chain is tested for an enumerate op, and those ops are called in order. The properties each op adds to the properties vector are added to the set of values the for-in loop will iterate over. All of this is nonstandard.
129	JSNewResolveOp	JSAPI Reference, Obsolete, SpiderMonkey
		Like JSResolveOp, but flags provide contextual information about the property access.
130	JSObject	JSAPI Reference, SpiderMonkey
		Objects are made up of the following parts:
131	JSObjectOp	JSAPI Reference, Obsolete, SpiderMonkey
		The callbacks of this type are:
132	JSObjectOps.defaultValue	JSAPI Reference, Obsolete, SpiderMonkey
		The JSObjectOps.defaultValue callback corresponds to the [[DefaultValue]] method defined in ECMA 262-3 §8.6.2.6. Many expressions in the ECMAScript language, such as a+b, involve implicit conversion of the operands using [[DefaultValue]].
133	JSObjectOps.defineProperty	JSAPI Reference, Obsolete, SpiderMonkey
		Define obj[id], an own property of obj named id, having the given initial value, with the specified getter, setter, and attributes.
134	JSObjectOps.destroyObjectMap	JSAPI Reference, Obsolete, SpiderMonkey
		No summary!
135	JSObjectOps.dropProperty	JSAPI Reference, Obsolete, SpiderMonkey
		The following contract governs JSObjectOps callers and implementations:
136	JSObjectOps.enumerate	JSAPI Reference, Obsolete, SpiderMonkey
		For native objects, the enumerate callback first checks the JSCLASS_NEW_ENUMERATE flag of the object's class. If the flag is present, enumerate simply delegates the call to JSClass.enumerate.
137	JSObjectOps.getAttributes	JSAPI Reference, Obsolete, SpiderMonkey
		Get or set attributes of the property obj[id]. Returns JS_FALSE on error or exception, else JS_TRUE with current attributes in *attrsp. If prop is non-null, it must come from the *propp out parameter of a prior JSObjectOps.defineProperty or JSObjectOps.lookupProperty call.
138	JSObjectOps.getProperty	JSAPI Reference, Obsolete, SpiderMonkey
		Get, set, or delete obj[id], returning JS_FALSE on error or exception, JS_TRUE on success. If getting or setting, the new value is returned in *vp on success.
139	JSObjectOps.getRequiredSlot	JSAPI Reference, Obsolete, SpiderMonkey
		Get and set a required slot, one that should already have been allocated. These operations are infallible, so required slots must be pre-allocated, or implementations must suppress out-of-memory errors. The native ops (js_ObjectOps, see js/src/jsobj.c) access slots reserved by including a call to the JSCLASS_HAS_RESERVED_SLOTS(n) macro in the JSClass.flags initializer.
140	JSObjectOps.lookupProperty	JSAPI Reference, Obsolete, SpiderMonkey
		Look for id in obj and its prototype chain, returning JS_FALSE on error or exception, JS_TRUE on success. On success, return null in *propp if id was not found.

154	JSRuntime	JSAPI Reference, NeedsContent, NeedsUpdate, SpiderMonkey
		In the JSAPI, JSRuntime is the top-level object that represents an instance of the JavaScript engine. A program typically has only one JSRuntime, even if it has many threads. The JSRuntime is the universe in which JavaScript objects live; they can't travel to other JSRuntimes.
155	JSSecurityCallbacks.contentSecurityPolicyAllows
		The JSSecurityCallbacks.contentSecurityPolicyAllows callback is called when a script attempts to access an object property. The callback can deny the script access to the property.
156	JSString	JSAPI Reference, NeedsContent, SpiderMonkey
		Conceptually, a JavaScript string is just an array of char16_t characters and a length. You should not rely on the structure of JSString, because it is subject to change; instead, treat JSString objects as opaque.
157	JSStringFinalizer	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		JSStringFinalizer::finalize finalizes external strings created by JS_NewExternalString.
158	JSTraceOp	JSAPI Reference, Reference, Référence(2), SpiderMonkey

173	JSVAL_TO_BOOLEAN	JSAPI Reference, Obsolete, SpiderMonkey
		JSVAL_TO_BOOLEAN casts the value v to a C integer, either 0 or 1. As a precondition, JSVAL_IS_BOOLEAN(v) must be true. That is, v must be either JSVAL_TRUE or JSVAL_FALSE. Otherwise the behavior is undefined.
174	JSVAL_TO_DOUBLE	JSAPI Reference, Obsolete, SpiderMonkey
		JSVAL_TO_DOUBLE casts a specified JS value, v, to a C floating-point number of type jsdouble. As a precondition, JSVAL_IS_DOUBLE(v) must be true. This function is not type-safe: if v is an integer, string, null, or anything else, the behavior is undefined.
175	JSVAL_TO_GCTHING	JSAPI Reference, Obsolete, SpiderMonkey
		JSVAL_TO_GCTHING casts a jsval, v, to a raw pointer. The type of the result is void *.
176	JSVAL_TO_INT	JSAPI Reference, Obsolete, SpiderMonkey

177	JSVAL_TO_OBJECT	JSAPI Reference, Obsolete, SpiderMonkey
		JSVAL_TO_OBJECT casts the argument, v, to type JSObject *. As a precondition, JSVAL_IS_OBJECT(v) must be true. That is, v must be either a reference to an object or JSVAL_NULL. This function is not type-safe: if v is not an object or JSVAL_NULL, the behavior is undefined.
178	JSVAL_TO_STRING	JSAPI Reference, Obsolete, SpiderMonkey
		JSVAL_TO_STRING casts the argument, v, to type JSString *. As a precondition, JSVAL_IS_STRING(v) must be true. This function is not type-safe: if v is not a string, the behavior is undefined.

186	JS_Add*Root	JSAPI Reference, Obsolete, SpiderMonkey
		These functions are obsoleted, use JS::PersistentRooted instead.
187	JS_AddArgumentFormatter	JSAPI Reference, Obsolete, SpiderMonkey
		JS_AddArgumentFormatter establishes formatter as the conversion function for format strings beginning with format in the context cx. On success, it returns JS_TRUE. Otherwise it returns JS_FALSE. (At the moment, JS_AddArgumentFormatter fails only if there is no memory available to record the registration.)
188	JS_AddExternalStringFinalizer	JSAPI Reference, Obsolete, SpiderMonkey
		Add a finalizer for external strings created by JS_NewExternalString using a type-code returned from this function, and that understands how to free or release the memory pointed at by JS_GetStringChars(str).
189	JS_AddFinalizeCallback	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		JS_AddFinalizeCallback add a callback function which the garbage collector calls at several points during garbage collection. rt is the runtime in which you specify the callback. cb is a pointer to the callback function to add.
190	JS_AliasElement	JSAPI Reference, Obsolete, SpiderMonkey
		JS_AliasElement assigns an alternate index number for an element or numeric property associated with a native object. obj is the object to which the element belongs. name is the element's current index in the object, and alias is the alternate index to assign to the element.
191	JS_AliasProperty	JSAPI Reference, Obsolete, SpiderMonkey
		JS_AliasProperty assigns an alternate name for a property associated with a native object. obj is the object to which the property belongs. name is the property's current name in the object, and alias is the alternate name to assign to the property.
192	JS_AlreadyHasOwnProperty	JSAPI Reference, SpiderMonkey
		These functions attempt to determine whether a property already exists on a specific JSObject without modifying the object. By design, this search may not find a property that other property lookup functions, such as JS_LookupProperty, would find.
193	JS_BeginRequest	JSAPI Reference, SpiderMonkey
		Indicates to the JS engine that the calling thread is entering a region of code that may call into the JSAPI but does not block.
194	JS_BindCallable	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		JS_BindCallable binds the given callable to use the given object as this.
195	JS_BufferIsCompilableUnit	JSAPI Reference, SpiderMonkey
		Given a buffer, return false if the buffer might become a valid JavaScript statement with the addition of more lines. Otherwise return true. The intent is to support interactive compilation - accumulate lines in a buffer until JS_BufferIsCompilableUnit is true, then pass it to the compiler.
196	JS_CStringsAreUTF8	JSAPI Reference, Obsolete, SpiderMonkey
		By default, all C/C++ strings passed into the JSAPI are treated as ISO/IEC 8859-1, also known as ISO-Latin-1. That is, each byte is treated as a Unicode character, and there is no way to pass in a string containing characters beyond U+00FF.

202	JS_ClearNewbornRoots	JSAPI Reference, SpiderMonkey
		The last GC thing of each type (object, string, double, external string types) created on a given context is kept alive until another thing of the same type is created, using a newborn root in the context. These newborn roots help native code protect newly-created GC-things from GC invocations activated before those things can be rooted using local or global roots.
203	JS_ClearNonGlobalObject	JSAPI Reference, Obsolete, SpiderMonkey
		JS_ClearNonGlobalObject removes all of obj's own properties, except the special __proto__ and __parent__ properties, in a single operation. Properties belonging to objects on obj's prototype chain are not affected.
204	JS_ClearPendingException	JSAPI Reference, SpiderMonkey
		JS_ClearPendingException cancels the currently pending exception in cx, if any. (There is a pending exception if the most recently thrown exception in cx has not yet been caught or cleared.)
205	JS_ClearRegExpStatics	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		JS_ClearRegExpStatics clears the pending input string and flags of the built-in RegExp object.
206	JS_ClearScope	JSAPI Reference, Obsolete, SpiderMonkey
		JS_ClearScope removes all of obj's own properties, except the special __proto__ and __parent__ properties, in a single operation. Properties belonging to objects on obj's prototype chain are not affected.
207	JS_CloneFunctionObject	JSAPI Reference, SpiderMonkey
		JS_CloneFunctionObject creates a new function object from funobj. The new object has the same code and argument list as funobj, but uses parent as its enclosing scope. This can be helpful if funobj is an extant function that you wish to use as if it were enclosed by a newly-created global object.
208	JS_CompareStrings	JSAPI Reference, SpiderMonkey
		JS_CompareStrings compares two JS strings, str1 and str2. If the strings are identical in content and length, JS_CompareStrings stores 0 in *result. If str1 is less than str2, *result is less than 0. If str1 is greater than str2, *result is greater than 0.

218	JS_ConcatStrings	JSAPI, JSAPI Reference, SpiderMonkey
		JS_ConcatStrings concatenates two JS strings, str1 and str2, and returns the result. The result could be the same as one of the input strings, if the other string is zero length. When the string concatenation fails NULL is returned.
219	JS_ConstructObject	JSAPI Reference, Obsolete, SpiderMonkey
		JS_ConstructObject creates a new object of the specified class, with the specified prototype and parent, then invokes a constructor function to initialize the new object. cx is a pointer to a context associated with the runtime in which to create the new object. clasp is a pointer to the class of object to create. proto and parent may specify objects to be used as the new object's prototype and parent. If either is NULL, the engine tries to find reasonable defaults.
220	JS_ContextIterator	JSAPI Reference, SpiderMonkey
		JS_ContextIterator steps through the set of contexts associated with the runtime rt. Each call to JS_ContextIterator returns the next context in the cycle.
221	JS_ConvertArguments	JSAPI Reference, Obsolete, SpiderMonkey
		JS_ConvertArguments provides a convenient way to translate a series of JS values into their corresponding JS types with a single function call. It saves you from having to write separate tests and elaborate if...else statements in your function code to retrieve and translate multiple JS values for use with your own functions.
222	JS_ConvertArgumentsVA	JSAPI Reference, Obsolete, SpiderMonkey
		JS_ConvertArgumentsVA is to JS_ConvertArguments as vprintf is to printf. See JS_ConvertArguments for further information.
223	JS_ConvertValue	JSAPI Reference, Obsolete, SpiderMonkey
		JS_ConvertValue converts a JavaScript value, v, to the specified type. On success, the converted value is stored in *vp. Typically users of this function set vp to point to v, so that if conversion is successful, v now contains the converted value.
224	JS_DecompileFunction	JSAPI Reference, SpiderMonkey
		JS_DecompileFunction generates the complete source code of a function declaration from a function's compiled form, fun.
225	JS_DecompileFunctionBody	JSAPI Reference, SpiderMonkey
		JS_DecompileFunctionBody generates the source code of a function's body, minus the function keyword, name, parameters, and braces, from a function's compiled form, fun.
226	JS_DecompileScript	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		JS_DecompileScript returns the source code of script. If script is a function, it calls JS_DecompileFunction. Otherwise, it returns the original source code of the script. If the script is not cached, it tries to load the source from file, and returns nullptr if an error happened while loading.
227	JS_DecompileScriptObject	JSAPI Reference, NeedsContent, SpiderMonkey
		FIXME: Please provide a description for this function.
228	JS_DeepFreezeObject	JSAPI Reference, Reference, Référence(2), SpiderMonkey

229	JS_DefaultValue	JSAPI Reference, SpiderMonkey
		Renamed to JS::ToPrimitive from JSAPI 44.
230	JS_DefineConstDoubles	JSAPI Reference, SpiderMonkey
		JS_DefineConstDoubles creates one or more properties for a specified object, obj, where each property consists of a double value.
231	JS_DefineElement	JSAPI Reference, SpiderMonkey
		JS_DefineElement defines a numeric property for a specified object, obj.
232	JS_DefineFunction	JSAPI Reference, SpiderMonkey
		JS_DefineFunction exposes a C/C++ function to scripts by defining a new method on an existing JavaScript object. It creates the new Function object as though by calling JS_NewFunction, then makes it a method of obj as though by calling JS_DefineProperty. JS_DefineUCFunction is the Unicode version of the function.
233	JS_DefineFunctions	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		JS_DefineFunctions creates zero or more functions and makes them properties (methods) of a specified object, obj, as if by calling JS_DefineFunction repeatedly.
234	JS_DefineObject	JSAPI Reference, SpiderMonkey
		JS_DefineObject creates a new object of the class clasp and assigns it to a new property of an existing object, obj. name is the property name to assign to obj to hold the new object, and flags contains the property attributes to set for the newly created property.
235	JS_DefineOwnProperty	JSAPI Reference, Obsolete, SpiderMonkey
		JS_DefineOwnProperty implements the ECMAScript defined function Object.defineProperty. So the same restrictions apply as for that function (e.g. it is not possible to change a non-configurable property).
236	JS_DefineProperties	JSAPI Reference, SpiderMonkey
		JS_DefineProperties creates properties on a specified object, obj.
237	JS_DefineProperty	JSAPI Reference, SpiderMonkey
		JS_DefineProperty defines a single property in a specified object, obj. JS_DefineUCProperty is the Unicode version of the function. JS_DefinePropertyById is the same but takes a JS::HandleId for the property name.
238	JS_DefinePropertyWithTinyId	JSAPI Reference, Obsolete, SpiderMonkey
		JS_DefinePropertyWithTinyId defines an object property with a tiny id. JS_DefineUCPropertyWithTinyId is the Unicode version of the function. Except for the tinyid parameter, these functions behave exactly as JS_DefineProperty and JS_DefineUCProperty. See those functions for more details.
239	JS_DeleteElement	JSAPI Reference, SpiderMonkey
		JS_DeleteElement removes a specified element or numeric property, index, from an object, obj. If an object references an element belonging to a prototype, the element reference is removed from the object, but the prototype's element is not deleted. If deletion is successful, JS_DeleteElement returns true. Otherwise it returns false.
240	JS_DeleteElement2	JSAPI Reference, Obsolete, SpiderMonkey
		JS_DeleteElement2 removes a specified numeric property, index, from an object, obj. If obj inherits the specified property from a prototype, the property is removed from the object, but not from the prototype. If deletion is successful, JS_DeleteElement2 stores true to *succeeded and returns true. Otherwise it returns false and the value of *succeeded is undefined.
241	JS_DeleteProperty	JSAPI Reference, SpiderMonkey
		JS_DeleteProperty removes a specified property, name, from an object, obj. JS_DeletePropertyById is the same but takes a jsid for the property name. These functions are identical to JS_DeleteProperty2 and JS_DeletePropertyById2 except that they do not have an out parameter.
242	JS_DeleteProperty2	JSAPI Reference, Obsolete, SpiderMonkey
		JS_DeleteProperty2 removes a specified property, name, from an object, obj, and stores true or false in *succeeded. It behaves like the JavaScript expression delete obj[name]. JS_DeleteUCProperty2 is the Unicode version of the function. JS_DeletePropertyById2 is the same but takes a JS::HandleId for the property name.
243	JS_DestroyContext	JSAPI Reference, SpiderMonkey
		These functions destroy a context, cx. JS_DestroyContext additionally performs garbage collection to reclaim any memory that was being used by cx's global object. JS_DestroyContextNoGC does not perform garbage collection. JS_DestroyContextMaybeGC may or may not perform garbage collection; the engine makes an educated guess as to whether enough memory would be reclaimed to justify the work.
244	JS_DestroyIdArray	JSAPI Reference, SpiderMonkey
		JS_DestroyIdArray frees the ID array pointed to by ida.
245	JS_DestroyRuntime	JSAPI Reference, SpiderMonkey
		JS_DestroyRuntime frees the specified the JavaScript runtime environment, rt. Call JS_DestroyRuntime after completing all other JS API calls. JS_DestroyRuntime garbage collects and frees the memory previously allocated by JS_NewRuntime.
246	JS_DestroyScript	JSAPI Reference, Obsolete, SpiderMonkey

247	JS_DoubleIsInt32	JSAPI Reference, SpiderMonkey
		JS_DoubleIsInt32 returns true if d i sequal to *ip.
248	JS_DoubleToInt32	JSAPI Reference, Obsolete, SpiderMonkey
		JS_DoubleToInt32 converts a C floating-point number of type double to int32, a signed 32-bit integer.
249	JS_DropExceptionState	JSAPI Reference, SpiderMonkey
		This function destroys the specified JSExceptionState object, unrooting as necessary any attached exception object and freeing the memory resources associated with the JSExceptionState object.
250	JS_DumpHeap	JSAPI Reference, Obsolete, SpiderMonkey
		See bug 378261 for detail.
251	JS_DumpNamedRoots	JSAPI Reference, Obsolete, SpiderMonkey
		Each call to JS_AddNamedRoot creates a record in a table of named roots maintained by the garbage collector. JS_DumpNamedRoots provides a way for the application to access the contents of that table. It calls the dump function once for each named root in the given runtime rt. In pseudocode:
252	JS_EncodeCharacters	JSAPI Reference, Obsolete, SpiderMonkey
		JS_EncodeCharacters copies the characters of a jschar array into a char array, converting the 16-bit values to 8-bit values. If SpiderMonkey was built with JS_C_STRINGS_ARE_UTF8 defined or JS_SetCStringsAreUTF8 was called, the string is converted to UTF-8.  Otherwise each character is simply truncated to 8 bits.
253	JS_EncodeString	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		JS_EncodeString and JS_EncodeStringToUTF8 convert the specified JavaScript str to a C string (an array of 8-bit chars).
254	JS_EncodeStringToBuffer	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		JS_EncodeStringToBuffer converts the specified JavaScript str to a C string (an array of 8-bit chars) and fills the specified buffer with up to length bytes of the string. It returns the length of the whole string encoding or (size_t)-1 if the string can't be encoded as bytes. If the returned value is greater than the length you specified, the string was truncated.
255	JS_EnterCompartment	JSAPI Reference, SpiderMonkey
		No summary!
256	JS_EnterCrossCompartmentCall	JSAPI Reference, Obsolete, SpiderMonkey
		No summary!
257	JS_EnterLocalRootScope	JSAPI Reference, Obsolete, SpiderMonkey
		Scoped local root management allows native functions, getter/setters, etc. to avoid calling JS_AddRoot and JS_RemoveRoot to manage global roots temporarily.
258	JS_Enumerate	JSAPI Reference, SpiderMonkey
		JS_Enumerate gets the ids of all own properties of the specified object, obj, that have the JSPROP_ENUMERATE attribute. (The term own property refers to a property that is not inherited from the object's prototype.) This is not quite the same behavior as a JavaScript for...in loop, which converts all property ids to strings and also enumerates inherited properties.
259	JS_EnumerateDiagnosticMemoryRegions	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		JS_EnumerateDiagnosticMemoryRegions enumerates memory regions that contain diagnostic information intended to be included in crash report minidumps.
260	JS_EnumerateResolvedStandardClasses	JSAPI Reference, Obsolete, Reference, Référence(2), SpiderMonkey
		JS_EnumerateResolvedStandardClasses enumerates any already-resolved standard class ids into ida, or into a new JSIdArray if ida is NULL. Return the augmented array on success, NULL on failure with ida (if it was non-null on entry) destroyed.
261	JS_EnumerateStandardClasses	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		The global object's class's enumerate op should call JS_EnumerateStandardClasses(cx, obj), to define eagerly during for...in loops any classes not yet resolved lazily.
262	JS_ErrorFromException	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		If obj is an exception object, the exception will have (or be able to lazily create) an error report struct, and JS_ErrorFromException will return the address of that struct. Otherwise, it returns nullptr. The lifetime of the error report struct that might be returned is the same as the lifetime of the exception object.
263	JS_EvaluateScript	JSAPI Reference, Obsolete, SpiderMonkey
		JS_EvaluateScript compiles and executes a script in the specified scope, obj. JS_EvaluateUCScript is the Unicode version of the function.
264	JS_EvaluateScriptForPrincipals	JSAPI Reference, Obsolete, SpiderMonkey
		No summary!
265	JS_ExecuteRegExp	JSAPI Reference, SpiderMonkey
		JS_ExecuteRegExp and JS_NewRegExpObjectNoStatics execute the RegExp object, reobj, to the specified input string, chars, from *indexp index.
266	JS_ExecuteScript	JSAPI Reference, SpiderMonkey
		JS_ExecuteScript executes a previously-compiled script, script.
267	JS_ExecuteScriptPart	JSAPI Reference, Obsolete, SpiderMonkey
		JS_ExecuteScriptPart executes part of a previously compiled script, script. The part parameter must be either JSEXEC_PROLOG to execute the script prolog or JSEXEC_MAIN to execute the main section of the script.

410	JS_NewObjectForConstructor	JSAPI Reference, SpiderMonkey
		JS_NewObjectForConstructor creates a new object exactly as the given constructor would if invoked with new. This function does not run the code of the constructor function--it just creates the object.
411	JS_NewPlainObject	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		JS_NewPlainObject creates a new plain object, like new Object(), with Object.prototype as [[Prototype]].
412	JS_NewPropertyIterator	JSAPI Reference, Obsolete, SpiderMonkey
		Create an object to iterate over the enumerable own properties of obj, in arbitrary order. (This differs from longstanding for..in loop order, which uses the order in which obj's properties were defined. Note also that while for..in includes properties inherited from prototypes, iterator objects do not.)
413	JS_NewRegExpObject	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		JS_NewRegExpObject and JS_NewUCRegExpObject create a new RegExp instance. The flags from the built-in RegExp constructor properties ignoreCase, global, multiline, and sticky are OR'd in with the provided flags parameter.
414	JS_NewRuntime	JSAPI Reference, SpiderMonkey
		JS_NewRuntime initializes the JavaScript runtime environment. Call JS_NewRuntime before making any other API calls except JS_Init. JS_NewRuntime allocates memory for the JSRuntime and initializes certain internal runtime structures. maxbytes specifies the number of allocated bytes after which garbage collection is run. If parentRuntime is specified, the resulting runtime shares significant amounts of read-only state (the self-hosting and initial atoms compartments). It is recommended to make use of this for every runtime in a process after the first one.
415	JS_NewScriptObject	JSAPI Reference, Obsolete, SpiderMonkey
		JS_NewScriptObject returns the script object associated with the given JSScript.
416	JS_NewStringCopyN	JSAPI Reference, SpiderMonkey
		JS_NewStringCopyN allocates space for a JavaScript string and its underlying storage, and copies n characters from a C character array, s, into the new JSString. JS_NewUCStringCopyN is the Unicode version of the function. The two functions differ only in the type of the character array s; both functions create ordinary JavaScript strings, and all JavaScript strings are made up of 16-bit characters.
417	JS_NewStringCopyZ	JSAPI Reference, SpiderMonkey
		JS_NewStringCopyZ allocates space for a new JavaScript string and its underlying storage, and then copies the contents of a null-terminated character array, s, into the new string. On success, JS_NewStringCopyZ returns a pointer to the new JavaScript string. On error, it returns NULL.
418	JS_NewUCString	JSAPI Reference, SpiderMonkey
		JS_NewString creates and returns a new string, using the memory starting at buf and ending at buf + length as the character storage. JS_NewUCString is the Unicode version of the function.
419	JS_NextProperty	JSAPI Reference, Obsolete, SpiderMonkey
		On success, JS_NextProperty returns true, with *idp containing the id of the next enumerable own property to visit using iterobj, or JSID_VOID if there is no such property left to visit. On error, it returns false, and the value left in *idp is undefined.
420	JS_Now	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		JS_Now returns microseconds since the epoch, midnight, January 1, 1970 UTC.
421	JS_NumberValue	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		JS_NumberValue converts a C floating-point number of type double to JS::Value, the type of JavaScript values.
422	JS_ObjectIsDate	Date, JSAPI Reference, JavaScript, SpiderMonkey
		JS_ObjectIsDate() can be used to check if you are dealing with a Date object, or a Date object used across compartments (or windows or sites, in the browser embedding).  This function returns true if the object is a Date.
423	JS_ObjectIsFunction	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		JS_ObjectIsFunction tests whether obj is a function object (faster than comparing obj's class name to Function, but equivalent unless someone has overwritten the Function identifier with a different constructor and then created instances using that constructor that might be passed in as obj).
424	JS_ObjectIsRegExp	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		JS_ObjectIsRegExp determines if a specified object, obj, is a RegExp object. If so, JS_ObjectIsRegExp returns true. Otherwise it returns false.
425	JS_PSGS	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		These macros encapsulate the definition of JSNative-backed JSPropertySpecs, by defining the JSNativeWrappers for them.
426	JS_ParseJSON
		Parse a string using the JSON syntax described in ECMAScript 5 and return the corresponding value.
427	JS_PopArguments	JSAPI_Reference, Obsolete, SpiderMonkey
		JS_PopArguments frees the stack frame pointer previously allocated by JS_PushArguments and unroots the jsvals which have been associated with it (those returned by JS_PushArguments as well).
428	JS_PreventExtensions	JSAPI Reference, SpiderMonkey
		All JavaScript objects recognize the concept of extensibility: whether new properties may be added to the object.  In some situations, it may be convenient to prohibit new properties.  In JavaScript this may be accomplished using the Object.preventExtensions method.  The similar JSAPI method is JS_PreventExtensions.
429	JS_PropertyStub	JSAPI Reference, SpiderMonkey
		The stub functions are not designed to be called directly by a JSAPI application. Rather, they are convenient stand-ins anywhere the JSAPI requires callbacks of certain types. Examples at JSClass illustrate how stub functions can be used.
430	JS_PushArguments	JSAPI Reference, Obsolete, SpiderMonkey
		JS_PushArguments provides a convenient way to translate a series of native C/C++ values to jsvals with a single function call.
431	JS_PutEscapedString	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		JS_PutEscapedString and JS_PutEscapedString write str into buffer escaping any non-printable or non-ASCII character using \escapes for JS string literals. Guarantees that a NUL is at the end of the buffer unless size is 0. Returns the length of the written output, NOT including the NUL. Thus, a return value of size or more means that the output was truncated. If buffer is null, just returns the length of the output. If quote is not 0, it must be a single or double quote character that will quote the output.
432	JS_Remove*Root	JSAPI Reference, Obsolete, SpiderMonkey
		JS_RemoveRoot removes the variable that rp points to from the garbage collector's root set.
433	JS_RemoveExternalStringFinalizer	JSAPI Reference, Obsolete, SpiderMonkey
		Remove finalizer from the global GC finalizers table, returning its type code if found, -1 if not found.
434	JS_RemoveRootRT	JSAPI Reference, Obsolete, SpiderMonkey
		Unregisters a pointer to a GC thing so that it is no longer a member of the garbage collector's root set. This enables any pointed-at GC thing to be garbage collected as needed.
435	JS_ReportError	JSAPI Reference, SpiderMonkey
		JS_ReportError is the simplest JSAPI function for reporting errors. First it builds an error message from the given sprintf-style format string and any additional arguments passed after it. The resulting error message is passed to the context's JSErrorReporter callback, if any.
436	JS_ReportErrorNumber	JSAPI Reference, NeedsContent, SpiderMonkey
		These functions create a JSErrorReport, populate it with an error message obtained from the given JSErrorCallback, and either report it to the current error reporter callback or create an Error object and set it as the pending exception.
437	JS_ReportOutOfMemory	JSAPI Reference, SpiderMonkey
		Call JS_ReportOutOfMemory to report that an operation failed because the system is out of memory. When the JavaScript engine tries to allocate memory and allocation fails, it reports an error as though by calling this function.
438	JS_ReportPendingException	JSAPI Reference, SpiderMonkey
		If an exception is pending in the context cx, JS_ReportPendingException converts the exception to a string and reports it to the current error reporter.
439	JS_ResolveStandardClass	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		JS_ResolveStandardClass resolves id, which must contain either a string or an int, to a standard class name in obj if possible, defining the class's constructor and/or prototype and storing true in *resolved. If id does not name a standard class or a top-level property induced by initializing a standard class, store false in *resolved and just return true. Return false on error, as usual for bool result-typed API entry points.
440	JS_RestoreExceptionState	JSAPI Reference, SpiderMonkey
		This function permits to restore any previously saved exception state which was saved into a JSExceptionState object created by the JS_SaveExceptionState function.
441	JS_SET_TRACING_DETAILS	JSAPI Reference, SpiderMonkey
		Set debugging information about the next thing to be traced by a JSTracer.
442	JS_SameValue	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		SameValue slightly differs from strict equality (===) in that +0 and -0 are not the same and in that NaN is the same as NaN. The SameValue algorithm is equivalent to the following JavaScript:
443	JS_SaveExceptionState	JSAPI Reference, SpiderMonkey
		Saves the current exception state (that is, any pending exception, or a cleared exception state) associated with the specified context cx, and returns a JSExceptionState object holding this state. That object may then be used to restore again the context using JS_RestoreExceptionState, or discarded using JS_DropExceptionState. Either of those two functions frees any memory used by the JSExceptionState.
444	JS_SaveFrameChain	JSAPI Reference, SpiderMonkey
		These two functions are used to set aside cx's call stack while that stack is inactive. After a call to JS_SaveFrameChain, it looks as if there is no code running on cx. Before calling JS_RestoreFrameChain, cx's call stack must be balanced and all nested calls to JS_SaveFrameChain must have had matching JS_RestoreFrameChain calls.
445	JS_ScheduleGC	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		JS_ScheduleGC sets the nextScheduled parameter of GC.
446	JS_SealObject	JSAPI Reference, Obsolete, SpiderMonkey
		JS_SealObject prevents all write access to the object, either to add a new property, delete an existing property, or set the value or attributes of an existing property.
447	JS_SetAllNonReservedSlotsToUndefined	JSAPI Reference, SpiderMonkey
		JS_SetAllNonReservedSlotsToUndefined assignes undefined to all of obj's own properties, except the special __proto__ and __parent__ properties, in a single operation. Properties belonging to objects on obj's prototype chain are not affected.
448	JS_SetArrayLength	JSAPI Reference, SpiderMonkey
		JS_SetArrayLength sets the .length property of an object obj. length indicates the number of elements. JS_SetArrayLength(cx, obj, n) is exactly the same as setting the length property of obj to n using JS_SetProperty. This is true even if obj is not an Array object.
449	JS_SetBranchCallback	JSAPI Reference, Obsolete, SpiderMonkey
		If the callback returns JS_TRUE, the JS engine continues to execute the script.
450	JS_SetCallReturnValue2	JSAPI Reference, Obsolete, SpiderMonkey
		Calling JS_SetCallReturnValue2 indicates to the runtime that the native will return a value of type Reference.
451	JS_SetCheckObjectAccessCallback	JSAPI Reference, SpiderMonkey
		Set the runtime-wide check-object-access callback. This function is deprecated. In SpiderMonkey 1.8.1 and later, use JS_SetRuntimeSecurityCallbacks instead.
452	JS_SetCompartmentNameCallback	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		JS_SetCompartmentNameCallback sets callback function which will be called to name the compartment. If the runtime has no JSCompartmentNameCallback, a compartment will be named "<unknown>"</unknown>.
453	JS_SetContextCallback	JSAPI Reference, SpiderMonkey
		JS_SetContextCallback specifies a callback function that is automatically called when JSContexts are created or destroyed. Only one callback function may be specified per JS runtime. This function returns the previous context callback, if any, else NULL.
454	JS_SetDefaultLocale	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		JS_SetDefaultLocale sets the default locale for the ECMAScript Internationalization API (Intl.Collator, Intl.NumberFormat, Intl.DateTimeFormat).
455	JS_SetDestroyCompartmentCallback	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		JS_SetDestroyCompartmentCallback sets callback function which will be called when sweeping each compartment of the runtime, before deleting the compartment.
456	JS_SetElement	JSAPI Reference, SpiderMonkey
		JS_SetElement assigns a value to a numeric property of an object. It behaves like the JavaScript expression obj[index] = v.
457	JS_SetErrorReporter	JSAPI Reference, SpiderMonkey
		JS_SetErrorReporter enables you to define and use your own error reporting mechanism in your applications. The reporter you define is automatically passed a JSErrorReport structure when an error occurs and has been parsed by JS_ReportError. JS_SetErrorReporter
458	JS_SetExtraGCRoots	JSAPI Reference, SpiderMonkey
		Register externally maintained GC roots.
459	JS_SetFunctionCallback	JSAPI Reference, Obsolete, SpiderMonkey
		JS_SetFunctionCallback sets a C function to be called each time a JavaScript function is invoked or exits.
460	JS_SetGCCallback	JSAPI Reference, SpiderMonkey
		JS_SetGCCallback sets a callback function which the garbage collector calls at several points during garbage collection. rt is the runtime in which you specify the callback. cb is a pointer to the new callback function to use.
461	JS_SetGCParametersBasedOnAvailableMemory	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		JS_SetGCParametersBasedOnAvailableMemory adjusts the parameters of the garbage collection based on available memory.
462	JS_SetGCZeal	JSAPI Reference, SpiderMonkey
		JS_SetGCZeal sets the level of additional garbage collection to perform for a runtime, for the purpose of finding or reproducing bugs.
463	JS_SetGlobalObject	JSAPI Reference, Obsolete, SpiderMonkey
		This function is obsolete; see also JS_GetGlobalObject.
464	JS_SetICUMemoryFunctions
		Sets the memory allocation and deallocation functions used by the ICU internationalization library.
465	JS_SetInterruptCallback	JSAPI_Reference, Reference, Référence(2), SpiderMonkey
		These functions allow setting an interrupt callback that will be called from the JS thread some time after any thread triggered the callback using JS_RequestInterruptCallback. To schedule the GC and for other activities the engine internally triggers interrupt callbacks. The embedding should thus not rely on callbacks being triggered through the external API only.
466	JS_SetNativeStackQuota	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		No summary!
467	JS_SetObjectPrincipalsFinder	JSAPI Reference, SpiderMonkey
		Set the runtime-wide object-principals-finder callback. This function is deprecated. In SpiderMonkey 1.8.1 or later, use JS_SetRuntimeSecurityCallbacks instead.
468	JS_SetOperationCallback	JSAPI Reference, Obsolete, SpiderMonkey
		These functions allow setting an operation callback that will be called from the JS thread some time after any thread triggered the callback using JS_TriggerOperationCallback. To schedule the GC and for other activities the engine internally triggers operation callbacks. The embedding should thus not rely on callbacks being triggered through the external API only.
469	JS_SetOptions	JSAPI Reference, Obsolete, SpiderMonkey
		JS_SetOptions sets the option flags of a given JS context cx. This function returns a uint32 value containing the previous values of the flags.
470	JS_SetParent	JSAPI Reference, Obsolete, SpiderMonkey
		JS_SetParent sets an object's parent.
471	JS_SetPendingException	JSAPI Reference, SpiderMonkey
		JS_SetPendingException sets the current exception being thrown within a context. If an exception is already being thrown, it is replaced with the new one given.
472	JS_SetPrincipalsTranscoder	JSAPI Reference, SpiderMonkey
		Set the runtime-wide principals transcoder callback. This function is deprecated. In SpiderMonkey 1.8.1 or later, use JS_SetRuntimeSecurityCallbacks instead.
473	JS_SetPrivate	JSAPI Reference, SpiderMonkey
		If a JSClass has the JSCLASS_HAS_PRIVATE flag, each object of that class has a private field of type void * which the application may use for any purpose. It is especially useful for storing C/C++ data that should not be directly visible to scripts. For example, a Socket class might use the private data field to store the socket handle.
474	JS_SetProperty	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		JS_SetProperty assigns the value v to the property name of the object obj. It behaves like the JavaScript expression obj[name] = v. JS_SetUCProperty is the Unicode version of the function. JS_SetPropertyById is the same but takes a JS::HandleId for the property name.
475	JS_SetPropertyAttributes	JSAPI Reference, Obsolete, SpiderMonkey
		JS_SetPropertyAttributes sets the attributes for a specified property, name of an object obj. JS_SetUCPropertyAttributes is the Unicode version of the function.
476	JS_SetPrototype	JSAPI Reference, SpiderMonkey
		JS_SetPrototype sets the prototype object for a specified object. A prototype object provides properties that are shared by similar JS object instances. Ordinarily you set a prototype for an object when you create the object with JS_NewObject, but if you do not set a prototype at that time, you can later call JS_SetPrototype to do so.
477	JS_SetRegExpInput	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		JS_SetRegExpInput sets the pending input string of the built-in RegExp object to the specified input string. The JSREG_MULTILINE is set to multiline parameter, and other flags are all reset.
478	JS_SetScriptStackQuota	JSAPI Reference, Obsolete, SpiderMonkey
		Set the quota on the number of bytes that stack-like data structures can use when the runtime compiles and executes scripts. These structures also consume heap space, so JS_SetThreadStackLimit does not bound their size. The default quota is 32MB which is quite generous.
479	JS_SetThreadStackLimit	JSAPI Reference, Obsolete, SpiderMonkey
		No summary!
480	JS_SetVersion	JSAPI Reference, Obsolete, SpiderMonkey
		JS_SetVersion attempts to set the version of JavaScript to version for a specified executable script context, cx. The version comes from the JSVersion enumerated type.
481	JS_SetVersionForCompartment	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		JS_SetVersionForCompartment attempts to set the version of JavaScript to version for a specified compartment, compartment. The version comes from the JSVersion enumerated type.
482	JS_ShutDown	JSAPI Reference, SpiderMonkey
		Destroys all free-standing resources allocated by SpiderMonkey, not associated with any JSRuntime, JSContext, or other structure.
483	JS_StrictlyEqual	JSAPI Reference, SpiderMonkey
		JS_StrictlyEqual determines if v1 is strictly equal to v2 under the JavaScript === operator, as specified in ECMA 262-3 §11.9.6. If the comparison attempt was successful, the method returns true and stores the result in *equal; otherwise it returns false.
484	JS_StringEqualsAscii	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		JS_StringEqualsAscii and JS_FlatStringEqualsAscii compare string str and ASCII string asciiBytes.
485	JS_StringHasBeenInterned	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		JS_StringHasBeenInterned returns true if the string str is interned.
486	JS_StringHasLatin1Chars	JSAPI, JSAPI Reference, Reference, Référence(2), SpiderMonkey
		JS_StringHasLatin1Chars returns true iff the string's characters are stored as Latin1.
487	JS_StringIsFlat	JSAPI, JSAPI Reference, Reference, Référence(2), SpiderMonkey
		JS_StringIsFlat returns true if the string is flattened.
488	JS_StringToVersion	JSAPI Reference, SpiderMonkey
		JS_StringToVersion attempts to convert the version string to a JSVersion value. JS_StringToVersion may return any of the following values:
489	JS_SuspendRequest	JSAPI Reference, SpiderMonkey
		Suspends the calling thread's current request, if any, to allow the thread to block or perform time-consuming calculations.
490	JS_THREADSAFE	JSAPI Reference, SpiderMonkey
		JS_THREADSAFE was a compile-time option that enables support for running multiple threads of JavaScript code concurrently as long as no objects or strings are shared between them.
491	JS_ThrowStopIteration	JSAPI Reference, SpiderMonkey
		JS_ThrowStopIteration throws the appropriate StopIteration object for the function currently executing in cx.
492	JS_ToggleOptions	JSAPI Reference, Obsolete, SpiderMonkey
		JS_ToggleOptions toggles context-wide options. It is equivalent to JS_SetOptions(cx, JS_GetOptions(cx) ^ options).
493	JS_TracerInit	JSAPI Reference, Obsolete, SpiderMonkey
		JS_TraceChildren and other tracing APIs call the tracer callback for each traceable thing directly referenced by a particular object or runtime structure. It is the callback's responsibility to ensure the traversal of the full object graph, if desired, by eventually calling JS_TraceChildren on the passed thing. In this case the callback must be prepared to deal with cycles in the traversal graph.
494	JS_TypeOfValue	JSAPI Reference, SpiderMonkey
		JS_TypeOfValue examines a specified JS value, v, and returns its JS data type. The return value is always one of JSTYPE_VOID, JSTYPE_OBJECT, JSTYPE_FUNCTION, JSTYPE_STRING, JSTYPE_NUMBER, or JSTYPE_BOOLEAN.
495	JS_Unlock	JSAPI Reference, SpiderMonkey
		Unlock a previously locked JS run-time environment.
496	JS_ValueToBoolean	JSAPI Reference, Obsolete, SpiderMonkey
		JS_ValueToBoolean converts a specified JavaScript value, v, to a boolean value. It implements the ToBoolean operator specified in ECMA 262-3 §9.2. On success, JS_ValueToBoolean stores the converted value in *bp and returns JS_TRUE. On error or exception, it returns JS_FALSE, and the value left in *bp is undefined.
497	JS_ValueToECMAInt32	JSAPI Reference, Obsolete, SpiderMonkey
		JS_ValueToECMAInt32, JS_ValueToECMAUint32, and JS_ValueToUint16 convert a JavaScript value to various integer types as specified in the ECMAScript specification.
498	JS_ValueToFunction	JSAPI Reference, SpiderMonkey
		Convert a JS::Value to a JSFunction.
499	JS_ValueToId	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		JS_ValueToId converts a specified JS::Value, v, to a jsid. If v is an integer, *idp receives an integer jsid. Otherwise, if E4X support is enabled and v is an object, *idp receives an object jsid. Otherwise, *idp receives an interned string jsid based on the value of v. If v is not a string, it is converted to a string as if by calling JS_ValueToString.
500	JS_ValueToInt32	JSAPI Reference, Obsolete, SpiderMonkey
		JS_ValueToInt32 converts a specified JS value, v, to a 32-bit signed integer (-2147483648 to 2147483647). First it converts v to a floating-point number as if by calling JS::ToNumber. If the result is NaN, an infinity, or a number outside the 32-bit range, JS_ValueToInt32 reports an error and conversion fails. Otherwise, the floating-point number is rounded to the nearest integer value.
501	JS_ValueToNumber	JSAPI Reference, Obsolete, SpiderMonkey
		JS_ValueToNumber converts a JavaScript value to a number. It implements the ToNumber operator described in ECMA 262-3 §9.3.
502	JS_ValueToObject	JSAPI Reference, SpiderMonkey
		JS_ValueToObject converts a specified JavaScript value, v, to an object. On success, this function stores either NULL or a pointer to the resulting object in *objp and returns true. Otherwise it returns false and the value left in *objp is unspecified.
503	JS_ValueToSource	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		JS_ValueToSource converts a specified JavaScript value, v, to a JavaScript source.
504	JS_ValueToString	JSAPI Reference, Obsolete, SpiderMonkey
		JS_ValueToString converts a specified JavaScript value, v, to a string. It implements the ToString operator specified in ECMA 262-3 §9.8. The result is like the JavaScript expression ""+v.
505	JS_VersionToString	JSAPI Reference, SpiderMonkey
		JS_VersionToString attempts to convert the version to a const char * string representation. JS_VersionToString may return any of the following values:
506	JS_YieldRequest	JSAPI Reference, SpiderMonkey
		Momentarily suspend the current JSAPI request, allowing garbage collection to run if another thread has requested it.
507	JS_freeop	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		JS_freeop is a wrapper for js_free(p) that may delay js_free(p) invocation as a performance optimization as specified by the given JSFreeOp instance.
508	JS_malloc	JSAPI Reference, SpiderMonkey
		JS_malloc allocates a region of memory nbytes in size. On success, JS_malloc returns a pointer to the beginning of the region. As with the standard C function malloc, memory allocated by JS_malloc is uninitialized.
509	JS_updateMallocCounter	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		JS_updateMallocCounter decrements malloc counter of GC and the zone of the context.
510	OBJECT_TO_JSVAL	JSAPI Reference, Obsolete, SpiderMonkey
		OBJECT_TO_JSVAL casts obj from type JSObject * to jsval. If obj is NULL, the result is JSVAL_NULL.
511	PRIVATE_TO_JSVAL	JSAPI Reference, Obsolete, SpiderMonkey
		With PRIVATE_TO_JSVAL(), an application can store a private data pointer, p, as a jsval. This can be useful with reserved slots.
512	Property attributes	Attribute, JSAPI Reference, Reference, Référence(2), SpiderMonkey
		Some property attributes are defined in the ECMAScript standard, in ECMA 262-3 §8.6.1. SpiderMonkey additionally defines several non-standard property attributes.
513	STRING_TO_JSVAL	JSAPI Reference, Obsolete, SpiderMonkey
		STRING_TO_JSVAL casts a given JSString * to jsval. str must be a non-null pointer of type JSString *. The conversion always succeeds.
514	Stored value	JSAPI Reference, JavaScript, SpiderMonkey
		In the JSAPI, the stored value of an object property is its last known value. For a data property, this is exactly the same thing as the property's current value.
515	jschar	JSAPI Reference, Obsolete, SpiderMonkey
		jschar, a typedef for the standard C++ type char16_t, will be removed in JSAPI 38. Functions that use jschar will use char16_t directly. Embedder code should use char16_t, too. (See bug 1063962.)
516	jsdouble	JSAPI Reference, Obsolete, SpiderMonkey
		jsdouble is a C floating-point number type. It is defined to be a 64-bit, IEEE 754 compliant type. See ECMA 262-3 §8.5. Arithmetic on jsdouble values in C should behave exactly like the floating-point arithmetic in JavaScript, except that C and JavaScript may treat not-a-number values differently.
517	jsid	JSAPI Reference, Reference, Référence(2), SpiderMonkey
		jsid is either a 31-bit signed integer, interned string or object.
518	jsint	JSAPI Reference, Obsolete, SpiderMonkey
		jsint and jsuint are 32-bit integer types.
519	JSDBGAPI	JavaScript, SpiderMonkey

520	Parser API	API, Guide, JavaScript, SpiderMonkey
		Example:
521	Profiling SpiderMonkey	Guide
		1.) Get yourself an optimized libxul build of Firefox, with debugger info.
522	Running Automated JavaScript Tests	Automated testing, Build documentation, Guide, QA, SpiderMonkey
		The jstests shell harness is js/src/tests/jstests.py. Basic usage is:
523	Running Parsemark	SpiderMonkey, tests
		Here's how you get your mitts on it. The test files are not checked into the source tree because they're non-Mozilla JS code.
524	SavedFrame	SpiderMonkey
		A SavedFrame instance is a singly linked list of stack frames. It represents a JavaScript call stack at a past moment of execution. Younger frames hold a reference to the frames that invoked them. The older tails are shared across many younger frames.
525	Setting up CDT to work on SpiderMonkey	Developing Mozilla, Eclipse, IDE, SpiderMonkey, Tools
		For CDT to index all code, SpiderMonkey has to be built with debug information. The full process of and requisites for doing so are described here. Please follow those instructions up until the point of invoking configure.
526	Shell global objects	JavaScript, NeedsContent, SpiderMonkey
		These are the global objects that are set up automatically by the SpiderMonkey js command-line interpreter when you start the program.
527	SpiderMonkey Build Documentation	Build documentation, Guide, SpiderMonkey
		Use these instructions to build the latest SpiderMonkey source code.
528	Rebranding SpiderMonkey (1.8.5)	Build documentation, SpiderMonkey

529	SpiderMonkey Internals	Guide, JavaScript, NeedsUpdate, SpiderMonkey
		At heart, SpiderMonkey is a fast interpreter that runs an untyped bytecode and operates on values of type JS::Value—type-tagged values that represent the full range of JavaScript values. In addition to the interpreter, SpiderMonkey contains a Just-In-Time (JIT) compiler, a garbage collector, code implementing the basic behavior of JavaScript values, a standard library implementing ECMA 262-5.1 §15 with various extensions, and a few public APIs.
530	64-bit Compatibility	SpiderMonkey
		The following types or typedefs are always 64-bit on 64-bit platforms, and 32-bit on 32-bit platforms:
531	Bytecode Descriptions	SpiderMonkey
		This document is automatically generated from Opcodes.h by make_opcode_doc.py.
532	Bytecodes	SpiderMonkey
		SpiderMonkey bytecodes are the canonical form of code representation that is used in the JavaScript engine. The JavaScript frontend constructs an AST from the source text, then emits stack-based bytecodes from that AST as a part of the JSScript data structure. Bytecodes can reference atoms and objects (typically by array index) which are also contained in the JSScript data structure.
533	Functions	SpiderMonkey
		There are several flavors of JavaScript function. All are JSObjects of the same class, js_FunctionClass.
534	Garbage collection	Guide, NeedsContent, SpiderMonkey
		SpiderMonkey has a mark-sweep garbage collection (GC) with incremental marking mode, generational collection, and compaction. Much of the GC work is performed on helper threads.
535	Invariants	SpiderMonkey
		or, "The Zen of SpiderMonkey".
536	Property cache	SpiderMonkey
		SpiderMonkey's property cache is an internal data structure used to speed up property accesses in the interpreter and to communicate between the interpreter and JIT.
537	Self-hosted builtins in SpiderMonkey	JavaScript, SpiderMonkey
		All self-hosted code is strict, so self-hosted functions invoked in a null or undefined scope won't be run in the scope of the global object.
538	SpiderMonkey Internals: Thread Safety	Guide, SpiderMonkey
		This page describes implementation details of the SpiderMonkey JavaScript engine. It is mainly of interest to people working on SpiderMonkey itself. See JS_THREADSAFE for a gentler introduction to using SpiderMonkey in a multi-threaded application.
539	Tracing JIT	Deprecated, SpiderMonkey
		The tracing JIT in SpiderMonkey consists of a generic, low level component called nanojit which is co-maintained between Adobe and Mozilla, and a SpiderMonkey-specific high level component called jstracer. The nanojit component is language agnostic, and contains no knowledge about SpiderMonkey or any other part of the Mozilla codebase. The jstracer component consists of a monitor and a recorder. The monitor watches the executing SpiderMonkey interpreter. When the monitor determines that the interpreter has entered a region of code that would benefit from native compilation, the monitor activates the recorder. The recorder records the activity of the interpreter, using nanojit to build an efficient, native representation of the execution called a fragment. The monitor then calls into the native code stored in the fragment.

		DRAFT IN PROGRESS - This is a draft, and right now it's mostly just a copy of the 1.8.5 release notes.
545	SpiderMonkey 1.8.8	SpiderMonkey
		SpiderMonkey 1.8.8 is supported on all the platforms where Firefox INSERT-ACTUAL-FIREFOX-VERSION-NUMBER-HERE runs.
546	SpiderMonkey 17	SpiderMonkey
		SpiderMonkey 17 is supported on all the platforms where Firefox 17 runs.
547	SpiderMonkey 24	SpiderMonkey
		SpiderMonkey 24 is supported on all the platforms where Firefox 24 runs.  Compiling it requires a C++ compiler, and the JSAPI can only be used from C++ code.  (This change was motivated by garbage collector improvements, which lean quite heavily on C++'s support for RAII through constructors and destructors.)  If you are compiling with Microsoft's Visual Studio, note that the minimum supported version is MSVC10/2010: MSVC8/9 support has been dropped.
548	SpiderMonkey 31	SpiderMonkey
		SpiderMonkey 31 is supported on all the platforms where Firefox 31 runs.  Compiling it requires a C++ compiler, and the JSAPI can only be used from C++ code.  If you are compiling with Microsoft's Visual Studio, note that the minimum supported version is MSVC10/2010: MSVC8/9 support has been dropped.
549	SpiderMonkey 38	SpiderMonkey
		SpiderMonkey 38 is supported on all the platforms where Firefox 38 runs.  Compiling it requires a C++ compiler, and the JSAPI can only be used from C++ code.  If you are compiling with Microsoft's Visual Studio, note that the minimum supported version is MSVC10/2010.
550	SpiderMonkey 45
		SpiderMonkey 45 is supported on all platforms able to run Firefox 45.  Compiling it requires a C++ compiler, and the JSAPI can only be used from C++ code.  If you are compiling with Microsoft's Visual Studio, note the minimum supported version is MSVC 2013.
