React Hooks revolutionized functional components by providing a way to use state and lifecycle features without classes. Let's master the essential hooks.
useState Hook
The useState hook allows you to add state to functional components. It's simple yet powerful for managing local state.
useEffect Hook
useEffect handles side effects in functional components, replacing lifecycle methods like componentDidMount and componentDidUpdate.
- Fetch data on mount.
- Subscribe to events.
- Cleanup on unmount.
Custom Hooks
Create reusable logic with custom hooks. For example, a useFetch hook can encapsulate data fetching logic.
Advanced Hooks
Explore useContext for global state, useReducer for complex state logic, and useMemo/useCallback for performance optimization.
Best Practices
Always clean up effects, avoid unnecessary re-renders, and test your hooks thoroughly to ensure reliability.
