> Another things makes you advance in Typescript, is using from declare namespaces.
> For example you have a lot of type in your React app, you need to access to these types, but you must import them in current typescript. If you declare all type that you need them as globally, you can use declaration of typescript like following:
>
> ```typescript
> declare global {
>  type Locales = "en" | "fa" | "tr";
>  type Another = SampleInterface{ x: number, y: number }
> }
> ```
