587d8254367417b2b2512c71 从ES6中的集中删除项目 1 remove-items-from-a-set-in-es6

--description--

让我们使用delete方法练习从ES6集中delete 。首先创建一个ES6 Set var set = new Set([1,2,3]);现在使用delete方法从Set中删除一个项目。

set.delete1;
console.log[... set]//应该返回[2,3]

--instructions--

现在创建一个整数为1,2,3,4和5的集合。删除值2和5然后返回集合。

--hints--

您的集应包含值1,3和4

assert(
  (function () {
    var test = checkSet();
    return test.has(1) && test.has(3) && test.has(4) && test.size === 3;
  })()
);

--seed--

--seed-contents--

function checkSet(){
   var set = null;
   return set;
}

--solutions--

function checkSet(){
var set = new Set([1,2,3,4,5]);
set.delete(2);
set.delete(5);
return set;}
