Yes, aOut would be a promise. It would look like this:

    async function doA() {
        ...
        return "the-result-of-a";
    }

(Which returns a promise. Assuming execution reaches that last line of my sample code, the promise will resolve to "the-result-of-a" when you "await" it.)

> ...then basically doC() would needed to be re-written to handle when it gets a promised value instead of an actual value

Well, wait a minute... it wasn't written in the first place! Let's write it though. It would look like this:

   async function doC( param ) {
       ...
       // we use "await param" where we want to
       // access the value of param. e.g.:
       const paramValue = await param;

       ...
    }

So not bad.
