How to practise Promises, API fetches and async awaits

I've completed the entire front dev track, and everything is perfectly clear to me now, except the three mentioned. I think I understand Promised and the fetch method and I can follow them when I see it written out, but I need a lot more practise. Async awaits seem to make things more complicated instead of easier to me.

Does someone know good API's or projects to try and work out as a way of practising these concepts?

Thanks!

Maybe build an app that gets all songs for an artist on spotify:

  1. input for entering artist search
  2. list out results

Implement three times with promises, fetch, and async/await, and reflect on the differences.
