Reactjs 使用类generictype生成错误响应createContext

我是一名初级前端工程师，我试图创建Context名称StoreContext，它具有初始参数 类型为“类”。这是我的密码 （我使用npx创建下一个应用程序设置我的项目）

{
    "plugins": ["@babel/plugin-transform-destructuring"]
  }

babel.config.js

module.exports = {
    presets: ["@babel/preset-react","@babel/preset-env"],
    plugins: [
      ['@babel/plugin-proposal-decorators', { legacy: true }],
      ["@babel/plugin-transform-destructuring",{"useBuiltIns":true}]
  ],
  };

如何修复编译错误？ 那个语法的名称是什么

{}作为托多利斯特

{}作为TodoList

a“cast”。用于告诉typescript推断的类型实际上有点不同。@谢谢，您能发布或链接任何示例吗？
