@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.

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
