JavaScript Minification Guide
What Minification Does:
- • Removes unnecessary whitespace and newlines
- • Eliminates comments (except license comments)
- • Shortens variable and function names
- • Optimizes expressions and statements
- • Removes dead code and unused variables
- • Combines and optimizes string literals
Best Practices:
- • Always keep original source files
- • Test minified code thoroughly
- • Use source maps for debugging
- • Consider gzip compression after minification
- • Be careful with eval() and dynamic code
- • Preserve license comments for legal compliance
