A while back I set myself the challenge to learn React 18 ( the latest at the time of post ). I looked at a couple of books and also at a Udemy course that was going cheap during one of their offers, but the best course I ever found and learnt so much from was React Tutorial. Its made up of 75+ chapters which take you step by step through the whole of React. Its a little expensive at £75 but you get 5 years of access including updates when React updates. Well recommended
