I agree to some extent, though there is a point to make about going with the basics first. React isn’t really a Blackbox, it‘s mostly written in plain old TypeScript and the internals don’t really do anything you couldn’t write yourself. What you should do however is rather than starting with a big framework like React as a beginner, start out with the absolute basics in plain JS. Learn how the language works, learn to manipulate the DOM yourself. Then, when you understand the basics, you can start appreciating what React does for you and understand (to some extent) how the underlying systems work. Where I agree though is that you don’t have to learn all the basics before you can proceed. I’ve been writing frontend code in for about six years now and I catch myself learning something new about browsers, web infrastructure and JavaScript itself nearly every day. All this is to say, don’t be afraid to both start at the beginning and understand the basics, and skip ahead a few chapters and try new things and learn as you go.
