Minify JavaScript to reduce file size or beautify compressed JS for readability. Strips comments, whitespace, and shortens variable names — 100% client-side.
Minification removes all comments (single-line and multi-line), strips whitespace (spaces, tabs, newlines between tokens), and collapses code onto fewer lines while preserving functionality. This typically reduces file size by 20–50% before gzip, making pages load faster.
For production, JS minification is essential for performance. Combine with gzip/brotli compression for maximum savings — a 100KB script can easily become 25KB transferred.
