JS Minifier
Removes extra whitespace and comments from JavaScript. This tool is intended for quick cleanup and learning purposes — not a replacement for production build tools such as esbuild, Terser, or Webpack.
Example
This tool removes whitespace and comments only. It does not perform tree-shaking, dead code elimination, or variable mangling.
For production use, consider esbuild, Terser, or Webpack.
Input: // comment
const x = 1;
Output: const x=1;
