What's the diff between fetch and xhr type? Which one should I use? or Can someone explain the diff b

fetch’s promise-based flow is *so* much nicer than XHR’s callback hell.

But yeah, error handling’s a pain. Pro tip: wrap fetch in a helper function that checks `response.ok` and throws on bad statuses.

XHR’s still king for niche cases tho, like tracking upload progress.

Check out the Fetch API docs on MDN—super helpful for edge cases.
