> 3. You can only call a red function from within a red function

The base of most arguments against async. And it's false. You can call red from blue. And you should, sometimes.

Yes... But it's a PITA most of the time, right ? I'm not sure for JS, as I can't remember right now but it's a annoying as f*k in python at least

In JS it’s not an issue as long as you just fire and forget. Because calls to async functions essentially fork off tasks. No way to synchronise on them though.

Python (and rust) are coroutine based so calling an async function does essentially nothing, you need to acquire a runtime handle in order to run and resolve the coroutine.
