# Minify all JavaScript files
Unminified JavaScript adds hundreds of KB to page weight, slowing down load times especially on mobile networks where every byte counts.
## Quick Reference
- Enable minification in your build tool (Vite, webpack, etc.)
- Use Terser for modern JavaScript minification
- Enable tree-shaking to remove unused code
- Typical reduction: 50-70% file size savings
## Check
Verify that all JavaScript files are minified in production to reduce file size, remove comments, and optimize code for faster loading and execution.
