A JavaScript library for internationalization and localization using official Unicode CLDR JSON data.
Globalize is a JavaScript library for internationalization and localization that provides formatting and parsing for dates, numbers, currencies, messages, and more based on Unicode CLDR data. It solves the problem of displaying culturally appropriate formats (like date structures, number groupings, and currency symbols) for users in different locales, ensuring applications are globally usable.
JavaScript developers building web or Node.js applications that need to support multiple languages and regional formats, such as e-commerce platforms, content management systems, or any software with a global user base.
Developers choose Globalize because it is modular, relies on the authoritative Unicode CLDR dataset, works consistently across browsers and Node.js, and allows fine-grained control over locale data loading without embedding content, reducing bundle size and keeping data up-to-date.

Based on Unicode CLDR, the most extensive standard for locale data, ensuring cultural accuracy and frequent updates without library bloat, as noted in the README's philosophy.
Allows loading only specific modules (e.g., date, number) and supports formatter caching and compilation, reducing bundle size and improving performance in production builds.
Runs identically in browsers and Node.js, providing reliable i18n across client and server environments, which is highlighted in the design goals.
Includes time zone support for date formatting independent of user environment and ICU message format for complex pluralization and gender inflections.
Requires manual loading of CLDR and IANA time zone data separately, adding configuration steps and dependencies that can be cumbersome for quick projects.
Does not use Ecma-402 APIs, missing potential performance gains in modern environments where native formatting is available, as admitted in the README.
Understanding CLDR data structures and module dependencies (e.g., for currency formatting) requires deeper i18n knowledge, making it less accessible for beginners.
Migration from Globalize 0.x to 1.x was necessary, indicating past API instability that could affect long-term maintenance for early adopters.
