Globalize provides number formatting and parsing, date and time formatting and parsing, currency formatting, message formatting (ICU message format pattern), and plural support. Globalize is based on the Unicode Consortium's Common Locale Data Repository (CLDR), the largest and most extensive standard repository of locale data available.CLDR is constantly updated and is used by many large applications and operating systems, so you'll always have access to the most accurate and up-to-date locale data.Globalize needs CLDR content to function properly, although it doesn't embed, hard-code, or host such content.
Vanilla CLDR in its official JSON format (no pre-processing) is expected to be provided.
As a consequence, (a) Globalize avoids bugs caused by outdated i18n content.
Developers can use up-to-date CLDR data directly from Unicode as soon as it's released, without having to wait for any pipeline on our side.
(b) Developers have full control over which locale coverage they want to provide on their applications.
(c) Developers are able to share the same i18n dataset between Globalize and other libraries that leverage CLDR. Globalize is systematically tested against desktop and mobile browsers and
So, using it you'll get consistent results across different browsers and across browsers and the server.
Globalize doesn't use native Ecma-402 yet, which could potentially improve date and number formatting performance.
Although Ecma-402 support is improving among modern browsers and even Node.js, the functionality and locale coverage level varies between different environments (see Comparing Java Script Libraries slide 25).
Each language, and the countries that speak that language, have different expectations when it comes to how numbers (including currency and percentages) and dates should appear.
