Set用于存储任何类型的唯一值，无论是基本类型还是引用类型。只有值没有键严格类型检测存储，字符串数字不等同于数值型数字存储的值具有唯一性遍历顺序是添加的顺序，方便保存回调函数其实Set类型更多的是操作数据，而并非存储。基础知识声明定义以下示例演示出如何使用Set类型存储数据。<script>"use strict";
let set = new Set([1, "1"
最新的ES6规范引入了新的数据类型Map和Set
初始化Map需要一个二维数组，或者直接初始化一个空Map。Map具有以下方法：var m = new Map([['Michael', 95], ['Bob', 75], ['Tracy', 85]]);
m.get('Michael'); // 95
var m = new Map(); // 空Map
m.set('Adam'
