你还记得ES6传播运营商`...` ？ `...`可以在ES6中获取可迭代对象并将它们转换为数组。让我们创建一个Set，并检查传播函数。
|
||
|
||
> var set = new Set（\[1,2,3]）;
|
||
> var setToArr = \[... set]
|
||
> console.log（setToArr）//返回\[1,2,3]
|
||
|

在本练习中，我们将set对象传递给`checkSet`函数。它应该返回一个包含Set值的数组。现在你已经成功学会了如何使用ES6 `Set()`对象，干得好！

assert(

(function () {
|

var test = checkSet(new Set([1, 2, 3, 4, 5, 6, 7]));
|

return DeepEqual(test, [1, 2, 3, 4, 5, 6, 7]);
|

})()

);
