Property attributes of ArrayBuffer.prototype
Writable no
Enumerable no
Configurable no


ArrayBuffer instances inherit from ArrayBuffer.prototype. As with all constructors, you can change the constructor's prototype object to make changes to all ArrayBuffer instances.


Specifies the function that creates an object's prototype. The initial value is the standard built-in ArrayBuffer constructor.
ArrayBuffer.prototype.byteLength Read only


Returns a new ArrayBuffer whose contents are a copy of this ArrayBuffer's bytes from begin, inclusive, up to end, exclusive. If either begin or end is negative, it refers to an index from the end of the array, as opposed to from the beginning.
