At what level do you need to know js to learn React, Angular framework or jQuery?

Question

JavaScript

Essence of the question: there is basic knowledge in javascript and there is a desire to learn further frameworks or js libraries, because. and at the main job they will give more projects on this topic and I want to study it myself. I've read several articles about it and still don't quite understand how everything is organized. Therefore, I wanted to ask, is it worth learning react or angular, or is it better to go deep into js?

Answer 1

React, Angular - you need to know a lot about JS.
jQuery - You can only know the basics of JS.

Answer 2

start with fundamental things - algorithms, data structures,
start with C ++, assembler,
and then you won't care what to code - it's a stupid matter of syntax and documentation
