JS - one huge file or many small files? - where to draw a line?

Question

Is there a good rule of thumb as to how big (in size) a JS file should be - that if it grows bigger than this it\'s good idea to split it into smaller files?

Answer 1

Develop in as many files as you want. Organize your code to keep development manageable.

Then, when you deploy, ship a minified/combined version of the code using a tool like Google Closure

This is what jQuery does. They ship one file, but the actual source code is much more organized.
