It was my understanding that async ensures that a function returns a promise by creating a new Promise only if a "thing" within the function is not a Promise.
I think this is not exactly accurated. We are getting a promise, which resolves with the same value as the promise from the return statement but ...it is not true that the exact same object is returned, not even when there is already a promise, it is a new one.
const p = Promise.resolve('foo');
async function foo() {
return p;
}
p === foo(); // false

BTW the article is super nice, thank you
Oh, didn’t know it worked that way. Thanks for your input @naimadozodrac
Again as we find out, the devil lies in the details
