How do I upgrade from XHR to Fetch API?

Upgrading from XHR to Fetch API is straightforward. You can replace your XHR calls with fetch() calls.

Can you show me a simple example of how to do that?

Sure! Instead of using var xhr = new XMLHttpRequest();, you can use fetch('url') to make a request.

What about handling responses and errors?

You can use .then() to handle responses and .catch() for errors. For example: fetch('url').then(response => response.json()).catch(error => console.error(error));.

Is there anything else I should be aware of when making this change?

Yes, remember that Fetch API returns promises, so you'll need to handle asynchronous code properly.
