javascript instance method
Intl.Locale.prototype.getCollations()
The getCollations() method of Locale instances returns a list of one or more collation types for this locale.
[!NOTE] In some versions of some browsers, this method was implemented as an accessor property called
collations. However, because it returns a new array on each access, it is now implemented as a method to prevent the situation oflocale.collations === locale.collationsreturningfalse. Check the browser compatibility table for details.
Syntax
getCollations()
Parameters
None.
Return value
An array of strings representing all collation types commonly used for the Locale, sorted in alphabetical order, with the standard and search values always excluded. If the Locale already has a collation, then the returned array contains that single value.
For a list of supported collation types, see Intl.supportedValuesOf().
Examples
Obtaining supported collation types
If the Locale object doesn’t have a collation already, getCollations() lists all commonly-used collation types for the given Locale. For examples of explicitly setting a collation, see collation examples.
const locale = new Intl.Locale("zh");
console.log(locale.getCollations()); // ["pinyin", "stroke", "zhuyin", "emoji", "eor"]
