587d8255367417b2b2512c73 使用Spread和Notes进行ES5 Set集成 1 use-spread-and-notes-for-es5-set-integration

--description--

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.logsetToArr//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!

--hints--

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]);
  })()
);

--seed-contents--

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

   // Only change code above this line
}

--solutions--

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