Ebook: Functional programming for mortals, with scalaz

This version was published on 2018-08-24
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.
This book uses Scalaz 7.2¹, the most popular, stable, principled and comprehensive Functional
Programming framework for Scala.
This book is designed to be read from cover to cover, in the order presented, with a rest between
chapters. Earlier chapters encourage coding styles that we will later discredit: similar to how we
learn Newton’s theory of gravity as children, and progress to Riemann / Einstein / Maxwell if we
become students of physics.
