Why Hooks?
React Hooks let you use state and other React features in function components. Before hooks, you needed class components for stateful logic — now everything is simpler and more composable.
The Big Three
- useState — add local state to a function component
- useEffect — run side effects after render (data fetching, subscriptions)
- useRef — persist mutable values across renders without triggering re-render
