What is Data Classes?

Data classes in Kotlin are special classes designed to hold data. The compiler automatically generates useful methods like equals(), hashCode(), toString(), componentN() functions (for destructuring), and copy() for you. This reduces boilerplate code when you primarily need a class to store and manage data.
