Preface

Why write Scala in Action when there are plenty of other Scala books on the market? What sets this book apart?

Scala in Action targets developers who not only want to learn the language but also want to build real-world applications using Scala. This book, in other words, covers not only the language and its latest features but also its ecosystem. My goal was to pack a sufficient number of real-world examples along with the right mix of theory so readers can easily become comfortable with the language.

Scala is a feature-rich language and it is not possible to cover all of its features in one book, at least one of a reasonable size. For that reason, I deliberately avoided some of the more advanced features of Scala. I encourage you to think of this book as your first on Scala, a foundation on which to build, before you dive into the more advanced features Scala has to offer.

I had a great time writing this book and I hope you have a great time learning this new and exciting language. I know you had a choice when it comes to Scala books; thank you for choosing this one.
