If we used `await Promise.all(names.map(name => fetch(...)))`, and call `.json()` on the results, then it would wait for all fetches to respond. By adding `.json()` directly to each `fetch`, we ensure that individual fetches start reading data as JSON without waiting for each other.

That's an example of how low-level Promise API can still be useful even if we mainly use `async/await`.

**Alternative modern approach**

Nowadays, we can achieve the same parallel execution cleanly using pure `async/await` combined with `Promise.allSettled`.

By wrapping the `fetch` and `.json()` calls inside an `async` callback for `.map()`, we ensure the requests execute independently. `Promise.allSettled` guarantees that a hard network failure in one request won't reject the entire batch, and using `.ok` simplifies the status check:

```js demo
const getUsers = async (names) => (await Promise.allSettled(
names.map(async (name) => {
const response = await fetch(`https://api.github.com/users/${name}`);
return response.ok ? await response.json() : null;
})
)).map(({ value = null }) => value);
```
