I highly recommend this talk (first half) for a great introduction of how React Hooks work internally, Ryan remakes the basics of hooks from scratch in 30 min:
I agree on 2 of the points of Jared Palmer but disagree on one:
- [agreed] The new "Concurrent Mode" will take things to a new order of complexity. I am actually very afraid of this, it seems like one of the things that might actually kill React, and I love working with React. I like it so much that I've invested into creating few React libraries to make my life easier.
- [agreed] React Hooks are difficult to get started with and to really understand them. IMHO this is mainly due to "React lifecycle", which is just a difficult concept (even with classes!). Life is not easy, and there are some times that there's complexity and you need to learn new complex concepts. No issue here IMHO.
- [disagree] React Hooks is currently magic. While it's a complex piece of software with many small details, once you understand fairly well the lifecycle (and React docs are great at this, and Dan Abramov's https://overreacted.io/ digs a lot deeper for the curious) all bugs are very clear.
I am currently mentoring someone in React who already knew HTML+CSS+JS, my recommendations are: get used to the syntax by practicing, learn the 3-4 typical libraries, and learn very well the lifecycle including how useState's setState and useEffect's dependencies work. That's most of day-to-day React work.
