ES6语法

ES6解构赋值：

栗子：

var person= {

name:'haha',

age:'18'

}

//ES5

var name = person.name

var age = person.age

//ES6

var {name, age} = person

ES6对象声明：

var name ="haha"

//es5

var person = {

    name:name,

    say : function(){

        console.log(this.name)

    }

}

//es6

var person = {

name,

say  () {

console.log(this.name)

}

}

ES6模块语法：

导入导出对应

export default routes

import routes from './routes'
导出什么值获取什么值。

export default function search(){
}

import search from './xx.js'
//search是一个函数

export routes

import {routes} from './routes'

箭头函数

//es5
    function resolve(res) {
      
        that.items = res.books;
    }
//es6
    var resolve = res => {
        this.items = res.books;
    }
