React Best Practices for Modern Applications

React continues to evolve, bringing new features and patterns that help developers build better applications. Here are the essential best practices for 2024.

Custom Hooks for Reusability

Custom hooks are one of React's most powerful features for code reuse. They allow you to extract component logic into reusable functions.

State Management Strategies

Choose the right state management approach for your application:

• useState for local state
• useContext for shared state
• useReducer for complex state logic
• External libraries for global state (Redux, Zustand)

Performance Optimization

Key techniques for optimizing React applications:

• React.memo for component memoization
• useMemo and useCallback for expensive computations
• Code splitting with React.lazy
• Virtualization for large lists

Testing Strategies

Comprehensive testing ensures your React applications are reliable and maintainable. Focus on:

• Unit tests for individual components
• Integration tests for component interactions
• End-to-end tests for complete user flows
