Updated for Scala 3
Dean is a well-known member of the Scala community, using Scala recently for streaming data systems at Lightbend and now at Domino Data Lab. This edition covers the new features of Scala 3, with comparisons to Scala 2, both to explain why the changes were made and how they improve Scala, and also to enable developers using mixed Scala 2 and 3 code bases to work effectively. The book is aimed at professional programmers who want a comprehensive, in-depth, yet pragmatic tour of Scala and best practices for using it.
Covers Scala 2.13
“Hands-on Scala teaches you how to use the Scala programming language in a practical, project-based fashion. This book is designed to quickly teach an existing programmer everything needed to go from “hello world” to building production applications like interactive websites, parallel web crawlers, and distributed systems in Scala. In the process you will learn how to use the Scala language to solve challenging problems in an elegant and intuitive manner.”

“The book for new developers who want to learn Scala and have fun. Creative Scala is aimed at developers who have no prior experience in Scala. It is designed to give you a fun introduction to functional programming. We assume you have some very basic familiarity with another programming language but little or no experience with Scala or other functional languages. We’ve chosen what we hope is a fun method to explore functional programming and Scala: computer graphics.”
“Functional programming (FP) is a style of software development emphasizing functions that don’t depend on program state… Functional Programming in Scala is a serious tutorial for programmers looking to learn FP and apply it to the everyday business of coding. The book guides readers from basic techniques to advanced topics in a logical, concise, and clear progression. In it, you’ll find concrete examples and exercises that open up the world of functional programming.”
"Getting code to do what we want it to do is perhaps the essence of our purpose as developers. So there are few things more intriguing or important than code that we think we understand, but that behaves rather contrary to our expectations. Scala Puzzlers is a collection of such examples in Scala. It is not only an entertaining and instructive way of understanding this highly expressive language better. It will also help you recognize many counter-intuitive traps and pitfalls and prevent them from inflicting further production bug hunt stress on Scala developers."
