What is the best method to reduce the size of my Javascript and CSS files?

Question

When working with large and/or many Javascript and CSS files, what\'s the best way to reduce the file sizes?

Answer 1

I found JSCompress a nice way to not only minify a JavaScript, but to combine multiple scripts. Useful if you're only using the various scripts once. Saved 70% before compression (and something similar after compression too).

Remember to add back in any copyright notices afterwards.
