Straightforward JavaScript async question.

```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 `done` logs immediately; use `for.of` if you want one request at a time.

```js
for (const id of ids) {
  await fetchUser(id)
}
console.log('done')

```

Yep, `for.of` is the right fix here if you need strict sequencing, because `forEach` just fires callbacks and keeps going.

Exactly, `for.of` with `await` is the clean way to keep each async step in order.

Yep - `for.of` with `await` is the straightforward sequential pattern, and it’s a lot clearer than trying to force order with `forEach`.

Yep, `for.of` with `await` is the clean sequential path here, and `forEach` won’t wait the way people expect.
