javascript instance method
Intl.Locale.prototype.getNumberingSystems()
The getNumberingSystems() method of 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 oflocale.numberingSystems === locale.numberingSystemsreturningfalse. 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.
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"]
