It took me a while to get comfortable with it too. The intuition I use is that in the past it used to be DrawWindow(), DrawWindow(), DisplayResultsofSlowFunction() and then the window would freeze for a few seconds, but with async/await theres a queue basically and your DisplayResultsOfSlowFunction() gets put to the side while awaiting so DrawWindow() can keep doin what its doin and your app doesnt appear to freeze, for a gui example (idk if that helps or if ye already knew it but just in case, for me all the internet explanations never talked about the scheduler for some reason so it took me a while).
