In addition to the excellent "Didact" article that explains how to _build_ React and its internals, I have an extensive "Guide to React Rendering Behavior" post that explains the user-visible behavior and mental model of rendering: - https://blog.isquaredsoftware.com/2020/05/blogged-answers-a-mostly-complete-guide-to-react-rendering-behavior/ https://blog.isquaredsoftware.com/2020/05/blogged-answers-a-... I can also recommend Dan Abramov's post "React as a UI Runtime": - https://overreacted.io/react-as-a-ui-runtime/ https://overreacted.io/react-as-a-ui-runtime/ and then of course the actual React docs for learning how to _use_ React: - https://react.dev/learn https://react.dev/learn
