The rising trend of reactive programming style fits the event based development paradigm of Vaadin very well. This presentation explores how the functional language features of Java 8 and other JVM languages combine with Vaadin to allow you to write clearer UI code. After introducing the languages and tools we start with a short application in Java 7, and evolve it step by step using the capabilities of Java 8 and Scala to demonstrate the benefits of each. No prior knowledge of Vaadin or the subject languages is needed to follow the presentation, a basic understanding of Java and interest in the modern reactive approach are sufficient.
