Scala Enums: Enhancing Type Safety in Your Applications

In Scala, enums are used to represent a finite set of values, typically as a replacement for Java's enum type. Introduced in Scala 3, they provide a type-safe way to work with fixed sets of constants. Enums in Scala can have parameters, methods, and even extend traits. They help in improving code readability and maintainability by providing a clear and concise way to define a collection of related values. Enums can also be pattern matched, adding to their versatility. They are especially useful in scenarios requiring a fixed set of constants, such as states or categories.

The code defines an enum TrafficLight with three values, each representing a traffic light color and its corresponding action. The TrafficLightDemo object contains a main method demonstrating the use of pattern matching to print actions based on the traffic light color.
