How to use in Typescript: type or interface?

Hi, Devs!

There are two main types for declaring the shape of a
object: interfaces and types. Let's think about type and interface implemented on Typescript language and its goals.

They are very similar and for most cases work the same way.
Both can be extended:

type Database = { connection: string; };
type UserRepo = Database & { user: User; };

interface Database { connection: string; }
interface UserRepo extends Database{ user: User; } 

We can extends an interface with two ways:

1 - Duplicating the interface:

interface Person {
  name: string;
}

interface Person {
  description: string;
}

2 - Using the reserved word: extends

interface Entreprise{
  description: string;
}

interface Person extends Enterprise{
  name: string;
}

A type alias can extend an Interface, and vice versa.

type Database = { connection: string; };

interface UserRepo extends Database {}

interface Database {}

type UserRepo = Database & { name: string; };

Discussion

1 - I prefer use only interface, because it is show us clearly what we are gonna do in oriented object programming;
2 - For programers of others languages would be more readable if we use interface instead of type;
3 - For a good practice in a clean code and a better software architecture I'd use only one interface instead of duplicate it. There're things that not always is an advantage and can complicate our clean code.

And what you think about this context?
