  • 2. Why Scala? Functional Programming (map, filter, foldLeft, foldRight, flatMap, etc..) Functions as First Class Citizen 2001 - EPFL Lambda/Closure Higher Order Functions, Currying and monads Parallel Collections (for multi-core processors) Evolutionary OO (case class, object, trait, pattern matcher, with*) You can use same jars/frameworks (Spring, Hibernate, Junit, etc..) Solid Documentation, Books, websites, blogs, community, twitter, etc… Static Typing BUT Scala has Duck Typing Runs on the JVM Java 1.3 - 2000 Awesome interoperability with Java NEW Javac 1/3 Same java tooling – Eclipse – Scala IDE (Not Perfect ) smaller Less noise, do more with less code than Java (LOC x2) Generics, Right? 2 Martin Odersky
