后续就可以通过vv3来直接生成下面的代码

{// Place your 全局 snippets here. Each snippet is defined under a snippet name and has a scope, prefix, body and // description. Add comma separated ids of the languages where the snippet is applicable in the scope field. If scope // is left empty or omitted, the snippet gets applied to all languages. The prefix is what is // used to trigger the snippet and the body will be expanded and inserted. Possible variables are: // $1, $2 for tab stops, $0 for the final cursor position, and ${1:label}, ${2:another} for placeholders. // Placeholders with the same ids are connected.// Example:// "Print to console": {// 	"scope": "javascript,typescript",// 	"prefix": "log",// 	"body": [// 		"console.log('$1');",// 		"$2"// 	],// 	"description": "Log output to console"// }"Print to console": {"prefix": "vv3","body": ["<template>","\t<div>","\t</div>","</template>","<script lang=\"ts\">","import { defineComponent } from 'vue'","export default defineComponent({","\tname:'App'","})","</script>",],"description": "Log output to console"}
