// var的问题
1. var 声明的变量往往会越域
2. var可以声明多次
3. var 会变量提升
// let
1. let 声明的变量有严格局部作用域
2. let 只能声明一次
3. let 不存在变量提升
4. let 声明时需要初始化
// const
1. 声明后不允许改变
//数组解构
let arr = [1,2,3];
let a = arr[0];
let b = arr[1];
let c = arr[2];
// 解构写法
let [a,b,c] = arr;
// 对象解构
const person = {
name: "jack",
age: 21,
language: ['java', 'js', 'css']
}
const { name: abc, age, language } = person;
// 声明对象简写
const age = 23

const person2 = { age, name }

let str = "hello.vue";
console.log(str.startsWith("hello"));//true
console.log(str.endsWith(".vue"));//true
console.log(str.includes("e"));//true
console.log(str.includes("hello"));//true
let ss = `<div>
<span>hello world<span>
</div>`;

console.log(info);
// 函数默认值
function add2(a, b = 1) {

// 不定参数

// 箭头函数，箭头函数this不能使用，对象.属性
// 例
let print = obj => console.log(obj);

// 例
let sum2 = (a, b) => a + b;

// 例
const person = {

const target = { a: 1 };
const source1 = { b: 2 };

// 对象的函数属性简写

// 对象深拷贝

// 合并对象
