Best practices for managing and deploying large JavaScript apps

Question

What are some standard practices for managing a medium-large JavaScript application? My concerns are both speed for browser download and ease and maintainability of developm

Answer 1

Read the code of other (good) javascript apps and see how they handle things. But I start out with a file per class. But once its ready for production, I would combine the files into one large file and minify.

The only reason, I would not combine the files, is if I didn't need all the files on all the pages.
