The problem with Promises is they don’t support cancellation. There’s AbortController for fetch, but it’s super awkward to use and browser support could be better. Anything beyond a POC that hits endpoints should abort pending requests whose results are no longer required. Observable is a better fit than Promise because it supports cancellation of the underlying resource when unsubscribing.
