I'm a big fan of Dave Ceddia's blog for bite-sized overviews of React Hooks. For example, the articles A Simple Intro to React Hooks or How the useContext Hook Works are excellent short introductions to a complex topic.
Yesterday, I found this gem: Thinking in React Hooks
The article compares class-based React components to React hooks in a concise, and visually appealing way.
I recommend checking out the article, even if you're already familiar with React hooks.
