Pro Does an excellent job of teaching functional programming
"Functional Programming in Scala" focuses on building a strong foundation in Functional Programming(FP). It fully explains FP concepts, including the "why" behind everything discussed.
Pro Creative, fun exercises
"Functional Programming in Scala" offers no shortage of exercises. Throughout the book, exercises and examples are plentiful to help the reader put what they're learning into practice for a better understanding.
Con Not for beginners
The material gets advanced pretty quickly. The material in the book is more effective if you already have an introduction to category theory and combinatorial analysis.
Con Only uses Scala as a medium to teach functional programming
Rather than focusing on teaching the language (such as the syntax), "Functional Programming in Scala" only uses Scala as the medium for teaching functional programming. This means the reader needs to already have some experience with Scala.
