Summary


We have finished the first chapter, and you should now have the basics to start a project on your own. We covered the installation of an IDE to code in Scala with the basic usage of the dedicated build tool named SBT. Three ways to explore Scala have been demonstrated, including the REPL to test simple Scala features, the IntelliJ worksheet to play with a small environment, and lastly a real project.

To code our first project, we used ScalaTest and the TDD methodology so that we had good code quality from the beginning. 

In the next chapter, we will write a complete program. It is a financial application that allows its users to estimate when they can retire. We will keep using the TDD technique and will further explore the Scala language, its development kit, and their best practices.
