Optimizing React Apps for Performance

Performance bottlenecks can creep into any React project. Here’s how to deal with them.

Techniques

1. Memoization

import React, { memo } from 'react';
const MemoizedComponent = memo(MyComponent);

2. useCallback and useMemo

Prevent re-creating functions or objects on every render.

3. Lazy Loading

const Component = React.lazy(() => import('./Component'));

4. Code Splitting

Use dynamic imports and suspense.

5. Virtualization

Use libraries like `react-window` for large lists.

Conclusion

Apply these techniques to create faster, smoother, and more scalable React apps.
