What is a data class?

To begin, we need to define what is a data class to fully understand the need of this package.

A data class is a class that only contains data and no logic. It is usually used to represent the state of an object or a response from an API. A data class should have the following properties:

• It should be immutable, meaning that once created, it cannot be modified.
• It should have a constructor that takes all the fields as parameters.
