In this chapter, we installed Scala for Jupyter. We used Scala coding to access data sets. We also saw how Scala can manipulate arrays. And we generated random numbers in Scala. There were examples of higher-order functions and pattern matching. We used case classes, saw examples of immutability in Scala, built collections using Scala packages, and looked at Scala traits.

In the next chapter, we will be looking at using big data in Jupyter.
