JavaScript · Middle · Question 63 of 75

Why do you need two `await`s here?

const res = await fetch("/api/user");
const user = await res.json();

✓Correct answer: fetch resolves when headers arrive; reading and parsing the body is a separate asynchronous step
2The second await retries the request
3It's a style choice; one await is enough

Explanation

The body may still be streaming when headers are available. Check res.ok before parsing, because 4xx/5xx responses don't reject.
