What is Scala?

From the Scala documentation:

  • Scala is an acronym for “Scalable Language”.
  • Scala is a pure-bred object-oriented language. Conceptually, every value is an object and every operation is a method-call. The language supports advanced component architectures through classes and traits.
  • Scala runs on the JVM. Java and Scala classes can be freely mixed, no matter whether they reside in different projects or in the same.
