遗憾的是，这仅是因为一个被称之为「导入省略」的功能而起作用。当 TypeScript 输出一个 JavaScript 文件时，TypeScript 会识别出 `Options` 仅仅是当作了一个类型来使用，它将会删除 `Options`

```ts
```JavaScript
// ./foo.js
export function doThing(options: Options) {
export function doThing(options) {
// ...
}

// ./bar.js
import { doThing } from './foo.js';

function doThingBetter(options: Options) {
function doThingBetter(options) {
// do something twice as good
doThing(options);
doThing(options);

首先，在一些场景下，TypeScript 会混淆导出的究竟是一个类型还是一个值。比如在下面的例子中， `MyThing` 究竟是一个值还是一个类型？

```ts
import { MyThing } from './some-module.js';
import { MyThing } from './some-module';

export { MyThing };
```
