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:
{
	"vue htm": {
		"scope": "html",
		"prefix": "vuehtml",
		"body": [
			"<!DOCTYPE html>",
			"<html lang=\"en\">",
			"",
			"<head>",
			"    <meta charset=\"UTF-8\">",
			"    <meta name=\"viewport\" content=\"width=device-width, initial-scale=1.0\">",
			"    <meta http-equiv=\"X-UA-Compatible\" content=\"ie=edge\">",
			"    <title>Document</title>",
			"</head>",
			"",
			"<body>",
			"    <div id=\"app\">",
			"",
			"    </div>",
			"    <script src=\"vue.min.js\"></script>",
			"    <script>",
			"        new Vue({",
			"            el: '#app',",
			"            data: {",
			"                $1",
			"            }",
			"        })",
			"    </script>",
			"</body>",
			"",
			"</html>",
		],
		"description": "my vue template in html"
	}
}
