找到文件、首选项、用户片段、 输入vue 会自动到vue.json页面中，
然后将以下代码复制、粘贴、保存。
回到以点vue结尾的文件 输入 vv 点击tab就会自动生成以下模板
{
// Place your snippets for vue here. Each snippet is defined under a snippet name and has a prefix, body and
// description. 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": {
// "prefix": "log",
// "body": [
// "console.log('$1');",
// "$2"
// ],
// "description": "Log output to console"
// }
"Print to console": {
"prefix": "vv",
"body": [
