Scala, the short form of Scalable language developed by Martin Odersky in 2003. Scala is a general-purpose programming language that supports both object-oriented as well as a functional programming paradigm. There are many reasons why Java developers should learn Scala and its interoperability with Java and multi-paradigm feature make at the best choice.
