用户代码块

在 VSCode 中，用户可以通过自定义代码片段（User Snippets）来快速插入常用的代码块。

官方文档

如何创建和使用用户代码片段：

点击用户片段后，即会弹出面板如下：

添加一个代码片段

  "片段名称": {
    "prefix": "快捷键",
    "body": ["代码片段"],
    "description": "描述说明"
  },

一些常用的代码片段

{
  // Place your 全局 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"
  // }
