//1、声明
//只读常量 const
//全局变量 var
//局部变量 let
//2、赋值
//2.1、按照对应位置，对变量赋值
let [a, b, c] = [1, 2, 3];
//2.2、Set 结构，也可以使用数组的解构赋值
let [x, y, z] = new Set(['a', 'b', 'c']);
//2.3、解构不仅可以用于数组，还可以用于对象
let { foo, bar } = { foo: 'aaa', bar: 'bbb' };
//3、对象拓展
const o = {
method() {
return "Hello!";
}
};
//4、Set 它类似于数组，但是成员的值都是唯一
//4.1、Set本身是一个构造函数，用来生成 Set 数据结构
const s = new Set();
[2, 3, 5, 4, 5, 2, 2].forEach(x => s.add(x));
for (let i of s) {
console.log(i);
}
// 2 3 5 4
//4.2、初始化
const set = new Set([1, 2, 3, 4, 4]);
