I've been a professional C, Perl, PHP and Python developer.
I'm an ex-sysadmin from the late 20th century.
These days I do more Javascript and CSS and whatnot, and promote UX and accessibility.
It doesn't matter so much that there's a lot out there. It's pretty evident what a piece of jQuery is doing when you look at it (unlike, say, a bit of react code where you need to understand a lot more concepts and it's frequently written to look "clever", most jQuery is basic DOM manipulation or using plugins. If you drop someone into a legacy jQuery environment, it's also so similar to modern, raw, Javascript that you can drop in a querySelectorAll if you don't understand what the jQuery's trying to do and it'll probably just work.
That’s a bloody good point. There is so much JQuery out there.
