CS 1 and CS2 Using Scala 2: A Decade of Experience

In 2010, the desire to teach CSI and CS2 in a single language led us to the adoption of a young language, called Scala, that supported both scripting and large-application object-orientation. We look at the original motivations for this choice and how it has worked. We also consider implications of this choice on later courses and look forward to how we expect language updates in Scala 3 to impact its use in this context.
