Should we master jQuery in web design?

Question

should we master jQuery to code shorter in javascript to make better web design?

Answer 1

Up to you. jQuery is often criticized for being sort of old-school, but I think jQuery is useful because it makes JavaScript easier to reason about and it takes care of a lot of browser compatibility issues. Even if you don't use it in every circumstance (generally not necessary to do so anyway), it's a nice tool to have up your sleeve, just in case.

Answer 2

I would advise you to master JavaScript ES6 instead.
