BaselineWidely available *

This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.

* Some parts of this feature may have varying levels of support.

TheRangeError object indicates an error when a value is not in the set or range of allowed values.

Description

ARangeError 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 toString.prototype.normalize(), or
when attempting to create an array of an illegal length with theArray constructor, or
when passing bad values to the numeric methodsNumber.prototype.toExponential(),Number.prototype.toFixed() orNumber.prototype.toPrecision().

RangeError is aserializable object, so it can be cloned withstructuredClone() or copied betweenWorkers usingpostMessage().

RangeError is a subclass ofError.

Constructor

RangeError(): Creates a newRangeError object.

Instance properties

Also inherits instance properties from its parentError.

These properties are defined onRangeError.prototype and shared by allRangeError instances.

RangeError.prototype.constructor: The constructor function that created the instance object. ForRangeError instances, the initial value is theRangeError constructor.
RangeError.prototype.name: Represents the name for the type of error. ForRangeError.prototype.name, the initial value is"RangeError".

Instance methods

Inherits instance methods from its parentError.

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)) {    throw new RangeError(      'The argument must be an "apple", "banana", or "carrot".',    );  }}try {  check("cabbage");} catch (error) {  if (error instanceof RangeError) {    // Handle the error  }}
