React Performance Optimization Tips

Performance is crucial for user experience. Here are practical tips to optimize your React applications.

Memoization

Use React.memo to prevent unnecessary re-renders of components.

const MyComponent = React.memo(({ data }) => {
  return <div>{data}</div>
})

Code Splitting

Split your code into smaller chunks to reduce initial load time.

const HeavyComponent = lazy(() => import('./HeavyComponent'))

Virtual Lists

For long lists, use virtual scrolling to render only visible items.

Profiling

Use React DevTools Profiler to identify performance bottlenecks.

Conclusion

By applying these techniques, you can significantly improve your React application's performance.
