Frequently Asked Questions
What is JavaScript minification?
JavaScript minification removes unnecessary characters like whitespace, comments, and line breaks from code to reduce file size without changing its behavior.
Does this tool rename variables?
No. This minifier removes whitespace and comments but does not rename variables. Full variable mangling requires an AST-based tool like Terser.
Is minified JavaScript harder to debug?
Yes. Minified code is harder to read. Use source maps in production to map minified code back to the original source for debugging.
