How do Ajax and Fetch compare in terms of performance?

Ajax and Fetch both serve to make HTTP requests, but Fetch is generally more modern and efficient. Fetch uses Promises, which can lead to cleaner code and better error handling.

Are there any specific performance metrics where one outperforms the other?

Yes, Fetch tends to have better performance in terms of handling multiple requests simultaneously due to its Promise-based architecture. However, Ajax can still be faster in certain scenarios, especially with older browsers.

What about browser compatibility? Is one better than the other?

Ajax has broader compatibility with older browsers, while Fetch is not supported in Internet Explorer. If you need to support legacy systems, Ajax might be the better choice.

Can you give me an example of when to use each?

Use Fetch for modern applications where you can leverage Promises and async/await for cleaner code. Use Ajax for legacy systems or when you need to support older browsers.
