It's especially beneficial for designing APIs where you don't care about if
users pass you a `Promise` or the actual data to work with.
Imagine a scenario where you would like to remove a set of files:
```js
async function remove(filesArray) {
const files = await filesArray;
/* … work with `files` here …*/
}
```
In the scenario above, you could pass an array of files, or a `Promise` that
resolves
to said array; the function accepts both.
