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]
--instructions--
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!

您的套装已正确退回!
assert(
(function () {
var test = checkSet(new Set([1, 2, 3, 4, 5, 6, 7]));
return DeepEqual(test, [1, 2, 3, 4, 5, 6, 7]);
})()
);
