在刚学习vue的时候，有些代码片段是经常写的，在vscode中写一个代码片段可以帮助快速生成。
生成步骤：
VSCode中的代码片段有固定的格式，所以我们一般会借助于一个在线工具来完成。
具体的步骤如下:
第一步，复制自己需要生成代码片段的代码;
第二步，vscode代码片段在线生成工具在该网站中生成代码片段;
第三步，在VSCode中配置代码片段;
在vscode中配置的步骤：
文件->首选项->配置用户代码片段->html.json->将复制的代码片段粘贴进去然后保存即可
此处附上刚学习vue需要使用的代码片段
{"create vue app": {"prefix": "vueapp","body": ["<!DOCTYPE html>","<html lang=\"en\">","","<head>"," <meta charset=\"UTF-8\">"," <meta http-equiv=\"X-UA-Compatible\" content=\"IE=edge\">"," <meta name=\"viewport\" content=\"width=device-width, initial-scale=1.0\">"," <title>Document</title>"," <script src=\"https://unpkg.com/vue@3/dist/vue.global.js\"></script>","</head>","","<body>"," <div id=\"app\">"," {{message}}"," </div>"," <script>",""," const app = Vue.createApp({"," data() {"," return {"," message: 'hello vue'"," }"," }"," })"," app.mount('#app')"," </script>","</body>","","</html>"],"description": "create vue app"}}
配置完成后，输入vueapp（prefix中的名字
）即可使用配置好的代码片段
