object indicates an error when a value is not in the set or range of allowed values.
Syntax
new RangeError([message[, fileName[, lineNumber]]])
Parameters

fileName

Description
A RangeError
is thrown when trying to pass a value as an argument to a function that does not allow a range that includes the value. This can be encountered when passing a value that is not one of the allowed string values to String.prototype.normalize()
, or when attempting to create an array of an illegal length with the Array
constructor, or when passing bad values to the numeric methods Number.prototype.toExponential()
, Number.prototype.toFixed()
or Number.prototype.toPrecision()
.
Properties

Methods
The global RangeError
contains no methods of its own, however, it does inherit some methods through the prototype chain.
RangeError
instances
Properties
RangeError.prototype.constructor
- Specifies the function that created an instance's prototype.
RangeError.prototype.message
- Error message. Although ECMA-262 specifies that
RangeError
should provide its ownmessage
property, in SpiderMonkey, it inheritsError.prototype.message
. RangeError.prototype.name
- Error name. Inherited from
Error
. RangeError.prototype.fileName
- Path to file that raised this error. Inherited from
Error
. RangeError.prototype.lineNumber
- Line number in file that raised this error. Inherited from
Error
. RangeError.prototype.columnNumber
- Column number in line that raised this error. Inherited from
Error
. RangeError.prototype.stack
- Stack trace. Inherited from
Error
.
Methods
Although the RangeError
prototype object does not contain any methods of its own, RangeError
instances do inherit some methods through the prototype chain.
Examples
Using RangeError
(for numeric values)
function check(n) { if(!(n >= -500 && n <= 500)) { throw new RangeError("The argument must be between -500 and 500."); } } try { check(2000); } catch(error) { if(error instanceof RangeError) { // Handle the error. } }
Using RangeError
(for non-numeric values)
function check(value) { if(["apple", "banana", "carrot"].includes(value) === false) { throw new RangeError("The argument must be an \"apple\", \"banana\", or \"carrot\"."); } } try { check("cabbage"); } catch(error) { if(error instanceof RangeError) { // Handle the error. } }
