Hey Gary, thanks for following my content - I very much appreciate it!

Your question is interesting because it sounds like you're doing GETs, which really shouldn't be async at all. What I see a lot of people do, and generally recommend, is to split big data loads into multiple calls and render components on screen as the data populates.

While data hasn't loaded, render placeholders that show something is working, like how Twitter or Facebook do it with the shapes that have the loading gradient animate across them.
