React Hooks Tutorial

React Hooks let developers use state and other React features in functional components, removing the need for class-based components in most modern applications.

useState and useEffect

The useState hook manages local component state, while useEffect handles side effects like data fetching, subscriptions, and manual DOM updates.

Custom Hooks

Custom hooks allow developers to extract and reuse stateful logic across multiple components, keeping code clean and reducing duplication.

Rules of Hooks

Hooks must be called at the top level of a component and only from React functions, ensuring consistent behavior across renders.
