Advanced React Patterns and Best Practices

# Advanced React Patterns and Best Practices As React applications grow in complexity, it's important to use patterns that promote maintainability and scalability. ## Essential Patterns ### 1. Compound Components Create flexible and reusable component APIs. ### 2. Render Props Share code between components using a prop whose value is a function. ### 3. Custom Hooks Extract component logic into reusable functions. ### 4. Context + Reducer Manage complex state across your application. ## Performance Optimization - Use React.memo for expensive components - Implement proper key props for lists - Lazy load components with React.Suspense - Optimize re-renders with useCallback and useMemo ## Testing Strategies Write tests that focus on user behavior rather than implementation details. ## Conclusion These patterns will help you write more maintainable React code that scales with your application's growth.
