Learn Functional Programming The Fast Way! (PDF)
NOTE: This book was previously named Learn Functional Programming Without Fear, but I didn’t think that properly reflects the book’s content, so I decided to rename it to Learn Functional Programming The Fast Way!
If you have a Disney Streaming account in 2022, you are a consumer of functional programming (FP) code written in Scala — what I call “Scala/FP.”
Similarly, if you have online financial accounts, read various online news sites, or use a gambling site like Caesars, you’re also consuming content generated by Scala/FP code.
Because of the concepts you’ll see in this book, Scala/FP code is trusted, rock-solid, and is used in massively-parallel programming and streaming environments.
AN INEXPENSIVE LITTLE BOOK, A HUGE GOAL
This little book has an audacious goal:
As affordably as possible, to help OOP developers who use languages like Java, Kotlin, Python, and C++ learn the concepts that take you to the cusp of using Scala’s two main FP libraries: Cats Effect and ZIO.
The book that in less than 250 pages of text that are written in a simple, conversational style — just like I was pair-programming next to you — with plenty of code examples.
To be clear, when I say “the cusp” of using those FP libraries, when you finish the book I want you to be able to look at the initial examples in the Cats Effect and ZIO documentation and think, “I know what they’re doing, and I know why they’re doing it.”
Because of my desire to make learning functional programming as affordable as possible for everyone, the price of this book is only $10.
That’s right, just $10.
(And it’s from the same guy that wrote the best-selling, highly-rated Functional Programming, Simplified, two editions of the Scala Cookbook, and co-wrote the Scala 3 Book for the official Scala website.)
