What is @formatjs/intl-locale?

@formatjs/intl-locale is a JavaScript library that provides utilities for working with locale identifiers.

This package allows you to parse, manipulate, and format locale identifiers according to the Unicode CLDR (Common Locale Data Repository) specification.

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));
