javaScript文件如下：
// Place your snippets for javascript 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": "cl",
"body": [
"console.log('$1');",
"$2"
],
"description": "Log output to console"
}
}
这样在编辑文件中输入'cl'然后按下tab可出现console.log('')
