# --description--
|
|
|
|
Do you remember the ES6 spread operator `...`?
|
|
|
|
`...` 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--
|
|
|
|
In this exercise we will pass a set object to the `checkSet` function. It should return an array containing the values of the Set.
|
|
|
|
Now you've successfully learned how to use the ES6 `Set()` object, good job!
|
|
|
|
# --hints--
|
|
|
|
`checkSet(new Set([1,2,3,4,5,6,7])` should return `[1, 2, 3, 4, 5, 6, 7]`.
|
|
|
|
```js
|
|
assert(
|
|
(function () {
|
|
var test = checkSet(new Set([1, 2, 3, 4, 5, 6, 7]));
|
|
return DeepEqual(test, [1, 2, 3, 4, 5, 6, 7]);
|
|
})()
|
|
);
|
|
```
|
|
|
|

|
```js
|
|
function checkSet(set){
|
|
// Only change code below this line
|
|
|
|
// Only change code above this line
|
|
}
|

```

```js

function checkSet(set){
|
|
return [...set];}
