Discussion on: Basics of Async and Await

Hi there, great set of notes on the subject!

I would add to your notes that returning any value from any async function makes it a promise as well. So returning a number will make it a Promise<number> in the end. Which can simplify asynchronous function definitions from this

function promiseNumber() {
    return Promise.resolve(123);
}

to this

async function promiseNumber() {
    return 123;
}

Of course, this will work with anything.
