Who this book is for
You are a software engineer who already has some knowledge of Scala, but wants to get more practical understanding of how to apply it in real-world application development, or you might simply want to have a useful reference to consult while designing applications. Having an understanding of the importance of using best practices and writing nice code is good; however, even if you don't, hopefully you will be convinced by the time you finish reading this book. Prior knowledge of design patterns is not required, but if you are familiar with some, this book will be useful, as we will be looking at them from the point of view of Scala.
