Summary
In this chapter, we covered how Scala makes it possible to write powerful Domain Specific Languages (DSLs) by providing a few interesting language features. We had a brief look at what DSLs are in general terms. We have also covered a DSL that you'll very likely be using if you're going to work with Scala professionally. Finally, we have implemented our own DSL.
We now come to the end of this book. In this book, we covered all the professional concepts of the Scala language, from setting up the development environment to writing your own custom DSLs. We covered the object-oriented and functional programming aspects of the Scala language. We also covered some useful libraries that are used in Scala, such as
Cats and
Doobie. Finally, we covered the additional resources and tools that will help you to stay up to date in the industry.
