    @devTea how?

    This is the only way I've figured it out so far:

    var gresult;
    Promise().then(function(result) {gresult = result; });
    return gresult;

    That's kinda the point of a promise. You don't know when the result will be available.

    @toriyaki return will return undefined. You don't have the result until it's passed to your "then" function.

    let result = await Promise(); works too. You need try catch to catch errors.

    It was all just a promise that it would simplify

    Promises are great when all you want is to console.log things.

    Promises are literally the worst implementation of "asynchronous" programming that I have ever encountered. Example:

    const retrievedUserEmail: string | null = await (await userApi.getUserByEmail(email)).email
