React Performance

The performance of a React application can be affected by multiple aspects, but some of the most common ones and their way to fix them are:

1. Reduce Re-renders:
   • Use React.memo and useCallback to avoid unnecessary updates.
   • Split large components into smaller, focused components.
2. Lazy Loading: Load components or routes on demand using React.lazy and Suspense.
3. Efficient State Management: Keep state local where possible and avoid overusing global state.
4. Minimize DOM Updates: Use keys in lists and avoid deeply nested props/state updates.
5. Code Splitting: Use Webpack or tools like react-loadable to split the bundle.
6. Profile and Debug: Use React Developer Tools to identify bottlenecks.
