We have reached the end of the chapter. In this chapter, we learned various aspects of setting up the development environment. We covered the structure of a Scala project, and we identified the use of sbt for building and running projects. We covered REPL, which is a command-line interface for running Scala code. We also covered how to develop and run code over the IDEA IDE. Finally, we implemented interactions with our simple chatbot application.

In the next chapter, we will cover the structure of a Scala program and dive deep into the object-oriented properties in Scala, such as like classes, objects, and traits. We will also cover the syntax for calling functions and various parameter-passing models.
