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

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.

For a list of supported numbering system types, see Intl.supportedValuesOf().

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"]
