How Do React Hooks Actually Work? React.js Deep Dive #3
In this video, we will learn how React Hooks actually work. We will do that by answering a number of questions about React Hooks. The first and most important question is Why do hooks rely on call order? (in other words Why can't they be called inside loops or conditions?). This has a lot to do with the fact that hooks are all about arrays and indexes. We will show this by reverse-engineering two of the most used React Hooks: useState and useEffect. The next question is Why isn't X a hook? The X in the question can be any hook proposition you can think of and the reason is that all React Hooks strictly follow 2 very important rules: composition and debugging. The last question we will answer is How does useState communicate with the renderer?
