From the post:
Scala is a modern, object-functional, multi-paradigm, Java-based programming and scripting language that is released under the BSD license. It blends the functional and object-oriented programming models. Scala introduces several innovative language constructs. It improves on Java’s support for object-oriented programming by traits, which are stackable and cannot have constructor parameters. It also offers closures, a feature that dynamic languages like Python and Ruby have adopted.
Scala is particularly useful for building cloud-based/deliverable Software as a Service (SaaS) online applications, and is also proficient to develop traditional, imperative code.
Scala helps programmers write tighter code. It uses a number of techniques to cut down on unnecessary syntax, which helps to make code succint. Typically, code sizes are reduced by an order of 2 or 3 compared to an equivalent Java application.
