Scala and design patterns

Scala is a hybrid language that combines features from object-oriented and functional languages. This not only allows it to keep some of the well-known object-oriented design patterns relevant, but also provides various other ways of exploiting its features to write code that is clean, efficient, testable, and extendable all at the same time. The hybrid nature of the language also makes some of the traditional object-oriented design patterns obsolete, or possible, using other cleaner techniques.
