How can I improve performance issues in my React and Angular applications?

I'm experiencing performance issues in my React and Angular applications. What can I do?

There are several strategies you can employ to improve performance. For React, consider using React.memo and useCallback to prevent unnecessary re-renders. In Angular, you can use OnPush change detection strategy.

What about optimizing the bundle size?

For both frameworks, you can use code splitting to load only the necessary parts of your application. Tools like Webpack can help with this.

Are there any specific tools to monitor performance?

Yes, you can use tools like Lighthouse for web performance audits, and React DevTools or Angular DevTools for profiling your applications.

How can I handle large lists efficiently?

For large lists, consider using virtualization libraries like react-window for React or Angular's CDK virtual scroll to render only the visible items.
