Concurrency made easy

Scala recommends the use of immutable data structures, immutable collections, use of value types, functional compositions, and transformations. Along with these, the use of actors and other concurrent constructs have made it so easy to write concurrent programs. Mostly, programmers do not have to deal with the complication of thread life cycle management, because of modern constructs such as actors and reactors available in the form of native support and through libraries. Akka is one of these toolkits available, written in Scala. Also, the use of futures and promises enables writing asynchronous code.
