Async-await vs then with not well behaving functions

gistfile1.txt

const shouldReturnPromise = () => { throw "test"; }

const withAsyncAwait = async () => {
  try {
    await shouldReturnPromise()
  } catch (e) {
    console.log('Handled: ' + e)
  }
}

const withPromise = async () => {
  shouldReturnPromise().then(null, () => console.log('Not Handled!'));
}

console.log(withAsyncAwait());
console.log(withPromise());

And in this case, you actually catch with Promise: https://codepen.io/jacktheripper-the-sans/pen/vjEdqw

In a perfect world it would not make a difference.
From what I've seen in reality, it is hard to make sure you always return promises and not throw errors without using async/await.

I understand that this is corner case (hence the title with not well behaving functions) ;) But it just makes me feel safer using async/await.

They try-catch on their side, so no needs for one more I think

My example was for the general discussion not for the particular case ;)

Yes, sure. But since the discussion has been running for the whole afternoon, I just wanted to make sure that we are aligned on how the current code behave and why try-catch wouldn't be required in that case because Promise.catch would have the same effect

Totally aligned 👍 The current code was moved from the Hype project. I would use async/await as I find it safer and simpler.
