IE has a limit of 31 style sheets (there are ways around that) but is there a limit to how many javascript files i can include? if i go above it, what happens?
i've got a page now with 40+ included js files.

- I'd love to know what needs you have for including 40 separate .js files. – dmackerman Commented Nov 11, 2010 at 20:47
- @zzzzBov: It's irrelevant. Some people just like to know these kind of limits. Optimization into single file is (imho) a step you perform when publishing the site to production. During development/debugging we want separate files because it makes live easier. – Stijn de Witt Commented Sep 11, 2013 at 7:09
- @dmackerman: 40 is nothing. If you try to approach a web application in a modular fashion and make ponents for things like a RichTextArea or a TreeView etc, it's very natural to give each ponent a separate file. Getting 40 files is than just a matter of placing many ponents on the same page. – Stijn de Witt Commented Sep 11, 2013 at 7:11

Reset to default 11I tried it myself and can now say that you can safely import and execute at least 200 JavaScript files in your HTML via script tag with the src-attribue with the following browsers:
- Win XP IE6,
- Win XP IE7,
- Win XP IE8,
- Windows 7 IE9,
- Mac OS X Lion Chrome 21,
- Mac OS X Lion Firefox 15,
- Mac OS X Lion Opera 12,
- Mac OS X Lion Safari 6.
Due respect, I think you're asking the wrong question. The correct question is: "I have 40+ JS include files...how do I fix it?"
Check out Google's article on reducing http round-trips, and the benefits of doing so. Combine, minify and deliver your files via gzip whenever possible.
The page not working is one concern, and a valid one...but why not side-step it and greatly improve your users' load time while you're at it by bining and minifying those files now, before you approach any limit? For mobile users round-trips are especially painful, but there's no reason not to offer a more optimal load experience to all your users.
