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.

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!

Tests

tests:
  - text: <code>checkSet(new Set([1,2,3,4,5,6,7])</code> should return <code>[1, 2, 3, 4, 5, 6, 7]</code>.
    testString: 'assert((function(){var test = checkSet(new Set([1,2,3,4,5,6,7])); return DeepEqual(test, [ 1, 2, 3, 4, 5, 6, 7 ]);})());'

Challenge Seed

function checkSet(set){
   // change code below this line

   // change code above this line
}

Solution

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