Scala

• Scala is a general-purpose programming language designed to express common programming patterns in a concise, elegant, and type-safe way
• Scala supports both Object Oriented Programming and Functional Programming

Scala -> compiler (scalac) -> Bytecode -> JVM -> Amazing Peformance/Rich Repository -> execute

Why Scala

Developers wnat more flexible languages to improve their productivity

This resulted in evolution of scripting languages like Python, Ruby, Groovy, Clojure etc

The optimizations performed by today’s JVM are extraordinary, allowing byte code to outperform natively compiled code in many cases.
