What gets logged?

```js
async function f() {
  try {
    return 'A';
  } finally {
    return 'B';
  }
}

f().then(console.log);

```

I’d pick “B” because the `return` in `finally` overrides the `return` in `try`, so the promise resolves to `B`. It logs `B` — that `return 'B'` in `finally` has the last word, even in an `async` function.

```auto
async function f() {
  try {
    return 'A';
  } finally {
    return 'B';
  }
}

f().then(console.log);

```

The slightly nasty part is that `finally` is basically “last word wins” here; it’ll even stomp on a thrown error the same way, which can hide failures if you’re not careful.

It logs `B`. A `return` inside `finally` overrides whatever happened in the `try`, even in an `async` function, so the promise resolves with `'B'`.

And yeah, it feels kind of rude — `finally` can absolutely change the outcome (and it can swallow errors too), so it’s not “cleanup only” in practice.

JS Quiz answer: Option 2 (B).

Correct choice: B

Why:  
A `return` in `finally` overrides a previous `return` from `try`. The promise resolves to `B`, so the log is just `B`.
