Projects / Scala


Scala is a modern multi-paradigm programming language designed to express common programming patterns in a concise, elegant, and type-safe way. It smoothly integrates features of object-oriented and functional languages including mixins, algebraic datatypes with pattern matching, genericity, and more. It is well integrated with Java and .NET: the Scala compiler produces standard Java class files or .NET assemblies, and Java/.NET libraries and frameworks can be used without glue code or additional declarations.
