Case classes are a fundamental part of modeling immutable data structures in Scala, allowing for expressive, type-safe representations that significantly simplify code.
By not needing to use 'new' to instantiate a case class, it streamlines object creation, and immutable properties provide a built-in 'copy' method for new instances.
The equality method in case classes ensures that objects with the same data are treated as equal, facilitating easier comparison and reducing bugs in code.
With features like automatic unapply for pattern matching and a default toString for debugging, case classes enhance the efficiency and maintainability of Scala programs.
