Babel is a widely used JavaScript compiler (transpiler) that converts modern ECMAScript 2015+ code, JSX, and TypeScript syntax into backwards-compatible JavaScript for older browsers and environments. It is a plugin-based toolchain with an ecosystem of presets, parsers, and integrations for webpack, browserify, gulp, and ESLint.
Use cases
- transpile es6 javascript to es5 for older browsers
- compile jsx for react projects
- use the latest javascript features before browser support
- run codemods to refactor code across a codebase
- polyfill missing features for target environments
- parse javascript into an ast for custom tooling
- integrate babel into webpack builds
When to choose
- you need to support older browsers or environments with modern JavaScript syntax
- you are building React or other JSX-based applications
- you want a plugin-based compiler with a mature ecosystem and integrations
- you need AST tooling for writing custom transforms or codemods
When to avoid
- you only target modern browsers and runtimes that natively support the syntax you use
- you want maximum build speed for pure TypeScript without Babel-specific plugins (consider esbuild or swc)
- you need type-checking, which Babel strips rather than verifies
