  1. Philipp Haller
    • A statically-typed programming language that integrates object-oriented and
    functional programming (https://www.scala-lang.org/)
    • Concise
    – Modern, compact syntax
    – Powerful type inference
    • Fully interoperable with Java and JavaScript (Scala.js)
    – Also: beta version of native code compiler (Scala Native)
    • About as fast as Java
    • Pushes the boundaries of what is possible to express in a type-safe way given
    the above properties of the language

    Motivation for Using Scala
    • Scala is an excellent choice for implementing interpreters and type checkers
    – This is the main task in the labs
    – Language features of particular interest: case classes and pattern matching,
    tuples, higher-order functions, etc.
    • Scala has received the highest international award for its significant impact on both
    industrial software development and programming language research 

    (ACM SIGPLAN Programming Languages Software Award)
    • In addition, learning a new language…
    – is beneficial when studying the principles of programming languages
    – can make you a better programmer, regardless of the languages you are going
    to use for future tasks
