# Understanding React Hooks React Hooks allow developers to use state and React features without writing class components. They streamline your code, make it more predictable, and reduce boilerplate. ## Key Hooks - **useState**: Manage component-level state. - **useEffect**: Handle side effects like data fetching or subscriptions. - **useContext**: Access React Context without prop drilling. By mastering these hooks, you'll simplify stateful logic and enhance code maintainability.
## Best Practices 1. **Keep Hooks at the Top Level**: Avoid calling Hooks inside loops or conditions. 2. **Create Custom Hooks**: Reuse stateful logic across components. 3. **Clean Up Effects**: Return a cleanup function in useEffect to prevent memory leaks. React Hooks foster a more functional approach to development, encouraging cleaner and more reusable code.
