The javascript is used mostly to drive the shell GUI, it shouldn't be taking seconds off all your mouse clicks. If there is really bad slowness, you should consider reporting that as a bug, it may not be the javascript that's at fault. The performance shouldn't be any worse than a typical lightweight web app running in firefox. That is of course if you ever end up using GNOME again for whatever reason.

I don't understand why you have to wonder what it's doing, the javascript is all self-contained and hosted locally. It's not using npm or anything like that. And the extensions are pretty much the same as any other app you use that supports plugins.

When I complain about GNOME performance, I am not making it up, learn that and bye.

I don't understand what the issue here is or what you want me to learn, those seem to all be bugs that were already fixed. If there are additional unfixed problems that others aren't aware of, and you're not making it up, then please mention those, and maybe I can help you get them reported.
