I'm primarily a backend but I've dabbled in frontend at times where needed, and I've always kinda felt there's value in polyfills if nothing else. Maybe you don't go full Angular/React but JQuery adds a lot of value for not much effort.
I realize JQuery is terribly unfashionable these days and maybe people would rather use some smaller niche polyfill library, but with how quickly the javascript world churns and deprecates, that is kind of a virtue tbh. JQuery is 16 years old and that's ancient in the javascript world, the Lindy effect says it will likely continue to be a pillar going forward as well. You're probably just better off using the standard even if you're not using all its capabilities.
