My current employer doesn’t really use jQuery. Most of the code is ES6 code. However, the agency that helped write the site a long time ago wrote some custom utility functions, and they mimic jQuery functionality. So, I am thinking to myself, “might as well used jQuery”

I really don’t think jQuery’s gzipped, compressed size is really that large in the scheme of things. I have seen third-party libraries and frameworks (especially ad-related libraries) that are way bigger.

If you don’t need single-page functionality, then jQuery is pretty good.
