Scala is a powerful object-oriented and functional programming language that has been long touted as the successor to Java or to replace Java. Well, that didn't just happen in the last few years. Scala has certainly made a lot of progress and established itself as a scalable programming language for big things. If you are a social media user and know Twitter, then let me tell you that they are using Scala, which proves that Scala has all the tools you need to build a high-performance, scalable application like Twitter, and Twitter is not the only company that is using Scala. If you look at Scala's website, you will find that IBM, Goldman Sachs, Verizon, and SAP are all using Scala.

You might already know that Scala is an acronym for scalable language, or should I say scalable programming language. It is actually a modern, multi-paradigm programming language designed to express common programming patterns in a concise, elegant, and type-safe way.
