Everything in the book applies to React applications, and in fact references view components like the ones in the frameworks you mentioned quite a few times. Even if the code you're writing is backed by a framework, in any non-trivial application you'll have to write interfaces other people (or your future self) have to consume and understand without much ceremony. The book goes through implementing internals that are easy to read, maintain and update, as well as interfaces that are easy to consume and extend. This advice applies to most JavaScript projects
