Great content! One question, however, is there any way we can ever get the return of async functions on the global scope? It seems that the variable we get would still live inside the scope of the self-invoking function? Suppose, I need to get a token from a token fetch request and use it for later api calls, I'd need the token returned. What's the proper way to do it?
