Intl.Locale.prototype.getNumberingSystems()

The getNumberingSystems() method of Intl.Locale instances returns a list of one or more unique numbering system identifiers for this locale.

Note: In some versions of some browsers, this method was implemented as an accessor property called numberingSystems. However, because it returns a new array on each access, it is now implemented as a method to prevent the situation of locale.numberingSystems === locale.numberingSystems returning false. Check the browser compatibility table for details.

Syntax

getNumberingSystems()

Parameters

None.

Return value

An array of strings representing all numbering systems commonly used for the Locale, sorted in descending preference. If the Locale already has a numberingSystem, then the returned array contains that single value.

A table of the standard Unicode numeral systems can be seen below.

Examples

Obtaining supported numbering systems

If the Locale object doesn't have a numberingSystem already, getNumberingSystems() lists all commonly-used numbering systems for the given Locale. For examples of explicitly setting a numberingSystem, see numberingSystem examples.

const arEG = new Intl.Locale("ar-EG");
console.log(arEG.getNumberingSystems()); // ["arab"]

const ja = new Intl.Locale("ja");
console.log(ja.getNumberingSystems()); // ["latn"]
