Babel is a JavaScript compiler that transforms modern ECMAScript code into backward‑compatible versions. It provides a rich plugin ecosystem for syntax transformation, polyfilling, and code‑mod operations.

Use cases

• Convert ES6+ code to ES5 for older browsers
• Apply JSX and TypeScript transformations in a build pipeline
• Run code‑mods to automatically refactor large codebases
• Polyfill missing JavaScript features for target environments
• Integrate with bundlers like Webpack or Rollup for on‑the‑fly transpilation

When to choose

• You need a mature, widely adopted tool for JavaScript syntax transformation
• Your project targets multiple browsers or Node versions with varying feature support
• You want a flexible plugin system to add custom transformations

When to avoid

• You require a zero‑runtime overhead solution that compiles to native code
• Your build environment does not support Node.js or npm tooling
• You need a lightweight parser without the full Babel ecosystem
