## Description
|
|
<section id='description'>
|
|
Do you remember the ES6 spread operator <code>...</code>?
|
|
<code>...</code> can take iterable objects in ES6 and turn them into arrays.
|
|
Let's create a Set, and check out the spread function.
|
|
|
|
```js
|
|
var set = new Set([1,2,3]);
|
|
var setToArr = [...set]
|
|
console.log(setToArr) // returns [ 1, 2, 3 ]
|
|
```
|

## Instructions
|
|
<section id='instructions'>
|
|
In this exercise we will pass a set object to the <code>checkSet</code> function. It should return an array containing the values of the Set.
|
|
Now you've successfully learned how to use the ES6 <code>Set()</code> object, good job!
