## What it is
Globalize is a JavaScript library for internationalization and localization built on official Unicode CLDR JSON data. It provides locale-aware formatting and parsing of numbers, currencies, dates, plural rules, relative times, units, and messages, working in both browsers and Node.js.

## Use cases
- format dates and numbers according to the user's locale
- format currency values for different countries
- parse user-entered dates and numbers in their local format
- handle plural rules across languages
- translate and format messages for multilingual apps
- format relative times like '5 minutes ago' per locale
- format units of measurement for different locales

## When to choose
- you need accurate, standards-based locale data from Unicode CLDR
- you need consistent i18n behavior across browser and Node.js
- you need fine-grained control over which i18n modules and data you load
- you need to parse locale-formatted user input back into dates and numbers

## When to avoid
- you only need the built-in browser Intl API and don't need CLDR parity
- you want a batteries-included i18n framework with routing and translation workflows
- your project is React-based and you prefer a React-specific i18n library

## Facets
- artifact type: library
- maturity: stable
- function: internationalization, parser, serialization
- domain: web-development, frontend
- platform: browser, cross-platform
- tags: i18n, l10n, cldr, unicode, date-formatting, number-formatting, currency, plurals, message-formatting, localization, nodejs
