Implicit classes in Scala allow developers to extend existing types like Int, enhancing their functionality without altering the original type's definition, improving both usability and readability.
In the given example, the implicit class RichInt introduces two methods: times, which executes a given function multiple times, and isEven, which checks if an integer is even.
By using implicit classes, Scala developers can add functionality in a concise manner without the verbosity associated with traditional inheritance, helping keep the code clean and maintainable.
This approach maintains type safety and leverages Scala's powerful type system, making it an effective pattern in Scala libraries to enrich types while keeping their base definitions intact.
