set.@@iterator

@@iterator属性的初始值与values属性的初始值是相同的函数对象。

句法

mySet[Symbol.iterator]

返回值

该Set 迭代器功能，这是values()默认功能。

例子

运用 [@@iterator]()

var mySet = new Set(
mySet.add('0'
mySet.add(1
mySet.add{}

var setIter = mySet[Symbol.iterator](

console.log(setIter.next().value // "0"
console.log(setIter.next().value // 1
console.log(setIter.next().value // Object

使用[@@iterator]()与for..of

var mySet = new Set(
mySet.add('0'
mySet.add(1
mySet.add{}

for (var v of mySet) {
  console.log(v
}
