Javascript Coding rules

Here are some rules I constrain myself to, and that can be useful for others :

1. Use good code conventions
2. Check your code: JSLint (javascript tools bundle for textmate make it automatic)
3. Minification of your code: JSMin
4. GZIP the code, don’t obfuscate: Minification v. Obfuscation

You will effectively reduce errors and debugging time by following those advices.
