What are the differences between XHR and Fetch API?

What are the differences between XHR and Fetch API?

XHR (XMLHttpRequest) is an older API for making HTTP requests, while Fetch is a modern alternative that uses Promises.

Can you explain why Fetch is preferred over XHR?

Fetch is preferred because it has a simpler syntax, supports Promises, and provides a more powerful and flexible feature set.

Are there any limitations of the Fetch API?

Yes, Fetch does not support progress monitoring for uploads and downloads, which XHR can handle.

How do I handle errors with Fetch?

You can handle errors in Fetch by using the .catch() method on the Promise, or by checking the response status.
