When to learn React?

Question

React

Hello. I have been learning JS for 3 weeks. I teach on the site learn.javascript.ru (I stumbled upon it by accident, it seems to be quite good), and I also watch videos on YouTube on JS to consolidate the material. I learn after C ++, so it's easy. So the site itself is divided into 3 rather weighty parts. My goal is to get into React as quickly as possible. Question: is it worth spending your time on learning all 3 parts or is there a certain base that will be enough to get started with React?

Answer 1

is it worth spending your time learning all 3 parts

Definitely yes.

is there a certain base that will be enough to start doing React?

There is, and it is much more than the described base on learn.js, namely:
Destructuring of tasks, and the ability to divide them into subtasks. OOP and the ability to see the code from the side of the architecture, to know the minimum design patterns.

Switching to React is worth it - when you swim freely in js, manipulate methods perfectly, know how to async and do not faint from callbacks. Otherwise, nothing will shine for you in React.
