es6

定义变量

const声明常量（只读变量）

// 1、声明之后不允许改变

const PI = "3.1415926"

PI = 3 // TypeError: Assignment to constant variable.

// 2、一但声明必须初始化，否则会报错

const MY_AGE // Missing initializer in const declaration

结构赋值

声明对象简写

箭头函数

箭头函数提供了一种更加简洁的函数书写方式。基本语法是：

参数 => 函数体

箭头函数多用于匿名函数的定义

创建默认页面基础代码

文件 => 首选项 => 用户片段 => 新建全局代码片段文件：

cpp 复制代码
