  1. Philipp Haller Scala • 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 1
  2. Philipp Haller 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 2
