Learning Scala is fun, but at times like it can be a daunting and frustrating experience. Like learning any new language I guess. I have found using the Scala command line interpreter can help. It turns out the the Scala IDE for Eclipse also provides an interactive interpreter. To start an interactive interpreter create a Scala project and add a Scala Worksheet (File | New… | Scala Worksheet). Give the Scala Worksheet a name, for example TestScala, and start testing and learning. After typing a statement hit CTRL+S to save and the results of each statement are displayed at the end of each line. How easy is this?
