Functional Programming in Scala ペーパーバック – 2014/9/23
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.
Purchase of the print book includes a free eBook in PDF, Kindle, and ePub formats from Manning Publications.
About the Technology
Functional programming (FP) is a style of software development emphasizing functions that don't depend on program state. Functional code is easier to test and reuse, simpler to parallelize, and less prone to bugs than other code. Scala is an emerging JVM language that offers strong support for FP. Its familiar syntax and transparent interoperability with Java make Scala a great place to start learning FP.

Paul Chiusano has been writing and shipping functional code in Scala since 2008 and is responsible for the introduction and growth of Scala usage at his company, Capital IQ. As part of this effort he co-designed a functional programming curriculum and taught an internal course for coworkers interested in learning FP. Paul is also a regular blogger and speaker on functional programming and Scala.
Rúnar Bjarnason is a self-taught programmer with 12 years of industry experience, with a focus on functional programming since 2008. Runar is a prolific blogger and occasional speaker on functional programming and the Scala programming language. He is a principal contributor to the Scalaz library for Scala and the Functional Java library for Java.

The authors do a great job at describing how one can reason about problems in a functional manner. While functional programming works really well for certain classes of applications and perhaps not so much for others, I found their teachings in the book useful for problem solving in general.
The best part for me were exercises. Each chapter offers a couple of problems I found very challenging, for those not accustomed to reasoning about functional concepts. I went over them in book club. The solutions always seem obvious when you read them, but even afterwards, trying to arrive at them yourself requires changing your approach to problem solving.
A very good read for anyone interested in Scala/functional programming.
There are some very good bits - the explanation of Monoids is the first time that I have really understood it.
I think if you already know a lot about functional programming(FP) from another language e.g Haskell, and you are trying to learn even more about FP, you will find this book very good and challenging with many good exercises, which will help you to use and understand Scala. However if you are new to Scala and FP, like I was when I started reading this book, you will probably also find the concepts weird and hard to understand and relate to (coming from a OOP background).
Alongside the book you also get an online version of it which I was not expecting. You can download it as PDF for on the go or sign up to the Manning website using the code present in the book to use an audio "live book" - so you can sit back and listen through it whilst commuting to work.
