The select() method of Intl.PluralRules instances returns a string indicating which plural rule to use for locale-aware formatting of a number.
Syntax
select(number)
Parameters
number- : The number to get a plural rule for.
Return value
A string representing the pluralization category of the number.
This can be one of zero, one, two, few, many, or other.
Description
This function selects a pluralization category according to the locale and formatting options of an Intl.PluralRules object.
These options are set in the Intl.PluralRules() constructor.
Examples
Using select()
First, create an Intl.PluralRules object, passing the appropriate locales and options parameters.
Here we create a plural rules object for Arabic in the Egyptian dialect.
Because the type is not specified the rules object will provide formatting for cardinal numbers (the default).
const pr = new Intl.PluralRules("ar-EG");
Then call select() on the rules object, specifying the number for which the plural form is required.
Note that Arabic has 5 forms for cardinal numbers, as shown.
pr.select(0); // 'zero'
pr.select(1); // 'one'
pr.select(2); // 'two'
pr.select(6); // 'few'
pr.select(18); // 'many'
