--- id: 587d8255367417b2b2512c73 title: Use Spread and Notes for ES5 Set() Integration challengeType: 1 videoUrl: '' localeTitle: 使用Spread和Notes进行ES5 Set()集成 --- ## 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.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! ## Tests ```yml tests: - text: 您的套装已正确退回! testString: 'assert((function(){var test = checkSet(new Set([1,2,3,4,5,6,7])); test === [ 1, 2, 3, 4, 5, 6, 7 ]})(), "Your Set was returned correctly!");' ``` ## Challenge Seed ```js function checkSet(set){ // change code below this line // change code above this line } ``` ## Solution ```js // solution required ```
...
var set = new Set([1,2,3]); var setToArr = [... set] console.log(setToArr)//返回[1,2,3]
