vscode怎样实现输入cl然后tab键出现console.lo

点击：文件→首选项→用户代码段→选择设置的语言→输入‘javaScript’
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('')
