I had a big post but deleted it all. I can more concisely say this:
The people here saying they still use it have so far demonstrated what I always say. If you're using jQuery, it's time to go back and relearn javascript. Most people should REALLY research the querySelector and querySelectorAll DOM methods.
I've always felt that jQuery encourages you to let your skills stagnate and you don't learn what your code is actually doing. Learn what the current spec has to offer. You don't need another dep just to target dom nodes ffs.
Does the same as the $ query but native in every browser in IE9+ and gives you a native node. Also more performant than getElementBy<whatever> methods.
