这种方式会添加实际的import,如果是个纯粹的类型声明文件(只含有@typedef的.js,类似于d.ts),JSDoc 方式会引入一个无用文件(只含有注释),而 TypeScript 方式则不存在这个问题 P.S.TypeScript 同时兼容这两种类型引入语法,更多相关讨论见Question: Import typedef from another file? 类型转换 类型转换(TypeScript ...

But to check whether Foo or Bar themselves are valid tag names, TypeScript would roughly just grab the types returned or constructed by Foo or Bar and check for compatibility with JSX.Element (or another type called JSX.ElementClass if the type is constructable). The limitations here meant th...
