Similarly, there are now a lot of things you can achieve with vanilla JS (or even vanilla CSS) that you used to only be able to achieve with jQuery, and frameworks like React and Angular are viewed more favorably. But lots of devs of a certain age know jQuery, even if they don't currently use it, and there is something to be said for familiarity. Honestly, if I needed to whip something up in a day, I would probably use jQuery rather than a heavier framework.
