When is it recommended to use a data class in your project?

A data class in Kotlin is recommended to be used when you need to create a simple class that mainly stores data and does not contain complex logic. Such classes automatically get methods like equals(), hashCode(), toString(), as well as copy() and componentN(), which simplifies working with them. For example, for data models, DTOs, or function parameters.

data class User(val id: Int, val name: String)

This reduces code and improves readability.
