What are @formatjs/intl-locale's main functionalities?
Parsing Locale Identifiers
This feature allows you to parse a locale identifier string into an object that contains its components, such as language, script, and region.
const { parse } = require('@formatjs/intl-locale');
const locale = parse('en-US');
console.log(locale);
Formatting Locale Identifiers
This feature allows you to format a locale object back into a string. This is useful for ensuring that locale identifiers are consistently formatted.
const { parse, format } = require('@formatjs/intl-locale');
const locale = parse('en-US');
const formattedLocale = format(locale);
console.log(formattedLocale);
Locale Comparison
This feature allows you to compare two locale objects to see if they are equivalent. This can be useful for determining if two different locale identifiers refer to the same locale.
const { parse, isEqual } = require('@formatjs/intl-locale');
const locale1 = parse('en-US');
const locale2 = parse('en-GB');
console.log(isEqual(locale1, locale2));
