I do not know much about JS, but I assume most of it is loaded by https://commons.wikimedia.org/wiki/MediaWiki:Common.js . Is there some other mechanism? How are default gadgets loaded? There is a lot of comments in Common.js, explaining purpose and authors/maintainers of each snippet of code, but even with that I often find it very hard to figure out which part of the interface is MediaWiki software and which is our local JS environment. I usually find out when I edit on other wikis and the tools or links I rely on are not there ("subpages" link comes to mind or link to template Transclusion count tool). I think it would be great if there was more documentation of the code and time frame for which it was intended. Many snippets seem to be patches for bugs with bug numbers in the documentation. We can probably check on status of those bugs.

This is too much, which negatively affects performance for our end users. Some of this is on WMF -- JS code we've deployed that we can optimize. But it would also be good to get community help with auditing site JS and gadgets that are loaded by default and that can be reduced in complexity, loaded only when needed, etc. We'll aim to provide better debugging tools to the community in future but wanted to point this out in case anyone already wants to take a closer look.
