A promise that resolves after a delay.

[Bob Myers]

Easy to write yourself:

```js
function wait(ms) {
  return function(v) {
    return new Promise(resolve => setTimeout(() => resolve(v), ms));
  };
}
```

Now you can do

```
Promise.resolve(42) . then(wait(1000)) . then( /* cb */);
```

and the 42 will get passed through the callback.
