Functional Programming for Mortals (The Digital Book)
Functional Programming for Mortals
with Scalaz
About the Book
This book is for the typical Scala developer, probably with a Java background, who is both sceptical and curious about the Functional Programming (FP) paradigm. This book justifies every concept with practical examples, including writing a web application.
Frequently Asked Questions
Q: How does it compare to the red book?
A: This book is blue.
Q: Where can I buy a physical copy?
