                            # 類型別名

類型別名用來給一個類型起個新名字。

## 簡單的例子

```ts
type Name = string;
type NameResolver = () => string;
type NameOrResolver = Name | NameResolver;
function getName(n: NameOrResolver): Name {
    if (typeof n === 'string') {
        return n;
    } else {
        return n();
    }
}
```

上例中，我們使用 `type` 創建類型別名。

類型別名常用于聯合類型。
