Frequently Asked Questions
What does JavaScript minification do?
It removes comments, unnecessary whitespace, and line breaks from JavaScript to reduce file size for faster page loads.
Does it rename variables?
This basic minifier focuses on whitespace and comment removal. For variable renaming (mangling), use a build tool like Terser or UglifyJS.
Will minification break my code?
Basic minification (whitespace/comment removal) is safe. The minified code is functionally identical to the original.
