JavaScript Best Practices
Before Minification:
Use const and let
Instead of var for better scoping
Remove console.log
Remove debugging statements before production
Use arrow functions
Where appropriate for cleaner syntax
After Minification:
Test thoroughly
Minification can introduce bugs
Keep source maps
For debugging minified code
Use CDN
Serve minified files from CDN for speed
