You don't need to learn useEffect until you need to plug arbitrary js libs and components into react. That's the intended use of useEffect. Using it for anything else is usually a bad idea.
- revskill 3y agoHow can you "fetch something when your state change ?". It's the main use case for useEffect.

- scotty79 3y agoYou can just trigger fetch in the function that does the state change.
- shortcake27 3y agoAgreed, this is the correct approach. Overusing effects makes control flow difficult to understand and has many unintended consequences. The misuse of effects is so widespread the React team had to address it with Strict mode in React 18.
