Consider this snippet.

```javascript
ids.forEach(async (id) => {
  await fetchUser(id);
});
console.log('done');

```

Why is this not sequential, and what simple loop should replace it.

`forEach` doesn’t await the async callback, so it fires all the fetches and `done` logs immediately.

Use `for...of` with `await` if you want strict sequence, though if order does not matter `Promise.all` is usually faster for something like 20 user fetches.
