What is the difference between defining a model as an interface or as a class in IONIC?

Question

I am a beginner in programming and my input language is Java.

Studying some projects with Ionic, I found one that used an interface to define a model, for example:

export interface Pessoa {
   nome: string;
   idade: number;
 }

Remember that the basic difference between a class and an interface is that the interface does not implement behaviors.

I know that Ionic is based on Typescript. Why adopt this practice?

I know that Typescript is not Java but as Java is my reference, where should be the methods of the class (or interface) Person in Ionic?

In the link below there is a more in-depth tutorial on the issue.

But briefly, if you want a model that has only attributes and no method, use an interface. Otherwise, create a class to implement methods.

But remembering that even so, an interface can be extended in a class.
