[Reading] From Javascript to React

[Reading] From Javascript to React

From Javascript to React https://nextjs.org/learn/foundations/from-javascript-to-react

Next.js has a very good (advanced) introductory lecture to shift dev's mind from Javascript to React.

I think this is a great resource for backend developer with some Javascript experience to enter the world of React gently, but with all the essential concepts ready.
