Today, a friend ask about the difference between `extends` and `implements`.

```typescript
class Media {
  format: string;
}
class Video extends Media {}
class Image implements Media {}
```

The short answer for him was:

extends: The class get all these methods and properties from the parent, so you don't have to implement.

implements: The class has to implement methods and properties. 

I hope this is can help someone with the same question.
