What's the key diff between fetch and xhr type for API requests? or Can someone explain the diff betw

fetch vs xhr type? fetch is like the cool new kid, xhr is the grandpa who still gets the job done.

fetch:
- Promise-based
- Cleaner syntax
- Less boilerplate

xhr:
- Callback hell
- More verbose
- But you can track upload progress (fetch can’t do that natively)

If you don’t need legacy stuff, stick with fetch. For error handling, just add a `.catch` or check `response.ok`.
