Scala is a general purpose programming language designed to express common programming patterns in a concise, elegant, and type-safe way. It has established itself as one of the main alternative languages on the Java Virtual Machine, being used by companies like Twitter and LinkedIn. Scala fuses functional programming (from which it borrows higher-order functions and closures, generic typing and immutable data structures) and object-oriented programming programming (from which it takes inheritance and encapsulation). It interoperates fully with Java, allowing a smooth transition and access to all existing Java libraries.
Scala’s lightweight syntax makes it easy to extend the language through DSLs. In this talk we are going to have a quick overview of Scala’s main features (closures, higher-order functions, implicits), and collection classes in the standard library. We’ll see how a new concurrency model, such as actors, can be added to the language through a library.
