Frequently Asked Questions
What does JavaScript minification do?
JavaScript minification removes unnecessary characters like comments, whitespace, and line breaks to reduce file size. It preserves all code functionality while making files smaller and faster to download.
Will minification break my JavaScript?
Proper minification should not break your JavaScript. However, always test minified code to ensure it works correctly. Keep original files as backups and use source maps for debugging.
How much file size reduction can I expect?
File size reduction varies but typically ranges from 30-60% depending on the original code. Files with lots of comments and whitespace see greater reductions.
Should I minify JavaScript in development?
Minify JavaScript for production use only. Keep original, readable code for development. Use build tools to automatically minify during deployment.
