## What it is
RequireJS is a JavaScript file and module loader implementing the AMD (Asynchronous Module Definition) API, optimized for in-browser use but also runnable in Node, Rhino, and Nashorn. It includes an r.js optimization tool that combines and minifies scripts and CSS for deployment.

## Use cases
- load javascript modules asynchronously in the browser
- manage script dependencies without global variables
- bundle and minify javascript files for production
- load text files and templates as module dependencies
- run amd modules in node or rhino
- load multiple versions of a module on one page
- load i18n string bundles in the browser

## When to choose
- maintaining a legacy codebase already built on AMD modules
- supporting very old browsers like IE6+ where native modules are unavailable
- you need a battle-tested loader with an optimizer for AMD-style code

## When to avoid
- starting a new project - use native ES modules or a modern bundler like webpack, Vite, or esbuild
- your project already uses CommonJS or ESM exclusively
- you need tree-shaking or modern build tooling
