There are a lot of similar questions but none of them really works when I test them so I don't think Im understanding them well. I modeled the below after this.Is there a way the following to return 3?

const fn = () => {
  let promise = new Promise(function(resolve, reject) {
    setTimeout(() => resolve(1), 1000);
  });

  promise.then(function(result) {
    return result * 2;
  });

  return promise
}

fn()

Why is it surprising that `return promise` returns a promise? – Barmar Nov 08 '19 at 21:24
It will always return a promise – Jonas Wilms Nov 08 '19 at 21:24
Any way i can return 3? – Kaisin Li Nov 08 '19 at 21:24
It runs asynchronously, it returns before the calculation is done. – Barmar Nov 08 '19 at 21:25
`fn().then(result => console.log(result))` – Barmar Nov 08 '19 at 21:26
still returning a promise – Kaisin Li Nov 08 '19 at 21:34
