### defer

Invokes the provided function after `wait` milliseconds.

Use `setTimeout()` to delay execution of `fn`.
Use the spread (`...`) operator to supply the function with an arbitrary number of arguments.

```js
const delay = (fn, wait, ...args) => setTimeout(fn, wait, ...args);
```

```js
delay(function(text) {
  console.log(text);
}, 1000, 'later'); // Logs 'later' after one second.
```
