What is Scala?

Scala (short for "Scalable Language") is a modern programming language created by Martin Odersky and first released in 2004, designed to run on the Java Virtual Machine while unifying object-oriented and functional programming in one language. Scala powers large-scale, data-intensive systems at companies like Twitter, LinkedIn, and Netflix, and is the language behind Apache Spark, the industry-standard engine for big data processing. Because it runs on the JVM, Scala code interoperates directly with existing Java libraries.

Note: Scala developers are among the highest-paid in the industry, largely because of Scala's central role in big data infrastructure like Apache Spark -- learning Scala is a strong path into data engineering.

object Main extends App {
  println("Hello, World!")
