Scala first appeared in 2004 on the Java platform. Then came along version 2.0 in March of 2006. The name Scala is a portmanteau of the words scalable and language, highlighting its ability to grow with its users’ demands. As a language, it is both object-oriented and functional. It is also language-interoperable with Java- source code in that Scala compiles to Java bytecode, which makes way for an executable that runs on the Java Virtual Machine (JVM). These languages also share libraries and use a curly-brace syntax.

Some among features that often amuse developers are of the likes of currying, type influence, immutability, lazy evaluation, and pattern matching.
