一些常用代码块经常需要重复书写，怎么解决痛点呢，这时候snippet是个解药。配置后只需输入自定义的key即可生成预设内容.

添加步骤

code -> Preferences -> User Snippets
选择New Snippets新建或者 Exiting Snippets修改
会打开 名称.code-snippets 文件，在此文件进行配置
使用时，直接输入 .snippets文件的 prefix值即可使用片段

.snippet文件一览

配置文件里可以使用一些变量，最常用的如 ${1}光标首先指向位置，$ {1}按Tab键后光标下一个位置，${0}光标最后位置。然后还有一些变量可以使用，如文件path当前时间等文章来源地址https://www.toymoban.com/news/detail-544369.html

	// Place your global 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"
	// }
