How many javascript files would be considered enough?

Hi there, I was just curious, I was experimenting with jQuery to use with my website, but I’m wondering how many external JavaScript files should I use to know when enough is enough? Already have 13 so far testing it on my desktop. Thanks for any help.

my website also was using 12 scripts (jquery) then i minify them and put some of them into several file (4 now) with the author intact,
correct me if I’m wrong the browser can only deal with 2 HTTP requests at one time so if we have lots of script the loading time would be longer and at first appearance the website looks messy


I would say use the least possible to get the job done and possibly combine some if it makes the site more efficient.
