How to learn React?
I learned JavaScript and JQuery, but I want to learn React.
Recommend books to study.

This is too unfounded a statement.
But if this is suddenly the case, then: according to normal - before getting into React, you should know -
functions, ordinary and arrow - how they differ, where they are used, callback, arrays (methods of working with arrays), objects (methods of working with objects ), spread operator, destructuring.
Further - in order to switch to React - you must begin to understand:
Why libraries and frameworks are needed, how they help when developing an application, what problems they solve.
- what is a component (what problems does it solve),
- why is the component approach the best when developing an interface (what problems does it solve),
what is JSX, what are its pros and cons in React, (what problems does it solve)
What is the difference between a functional and a class component (what problems does each of them solve and create)
What are props, state, dispatch, action, passing data through props, how redux works (it is desirable to know what is under the hood).
What is a reducer and observer,
why do we need a container component over a presentational component, and so on and so forth.
Everything that I described to you (30% of everything) - this is the level of the junior - is taken from the documentation, and at the first experience of developing your pet project. The blessing of books, the documentation suffices.
If you are swimming in moments like - you don’t know objects and arrays, why map is used, and how to make a simple component in vanilla JS - don’t get into React, it’s still too early.

Theory = 1, but practice will always be at the 0th index. This question would not have occurred to me. React books, what is it, documentation, what books? Books are needed as much as possible to master the basics of the language, or to deepen its intricacies, and the framework is an api built in the N language to simplify the work.
