Is it worth learning React without in-depth knowledge of Javascript?

Question

React

Good afternoon, I have been designing and integrating websites on different CMS for 2 years. I decided to develop in more depth in Front End development. Prior to that, I had experience with JS (jQuery + a couple of small Javascript functions). Writing small calculators, etc.
Having basic knowledge, you should immediately go to the study of React or still read a couple of books and practice on pure JS
Thanks

Deep JS is a loose concept.
I would advise you to follow the path of gaining knowledge through Google, books are not your helpers in this regard, only practice (you will get the theory from blogs, Google). Reading the book "You don't know JS" at the beginning of your career is the same as just learning to drive, trying to take lessons in the Nascar league.
As I did - take a conditional ToDo List, write it in pure JS. At this time, you will have a bunch of googling, errors, and so on. After you have written the body language, rewrite it for React. You will begin to understand the processes in your head, what tasks React solves, how much it speeds up the process, and so on.
Next, make a mini application in JS, let's say a task scheduler, an analogue of google keep, or another product that you have seen, and you can steal the visual component, or the logic of the functionality. How did you do it - write it in react. After such two pet projects - one small, and the second large, I would have gone over to an in-depth study of React, and would rather go to social security. Since you still won’t learn many features of companies in solo, and among other developers, the growth of a beginner grows exponentially.
Beginners think that React is a panacea for all ills, and shove it even where regular JS would be enough. Here is such a prof. deformation.

Basic minimum - data structures, array methods, closures, be able to google
