Learn Functional Programming The Fast Way! (PDF)
UPDATE: Please don’t pay for this book, especially for a dollar or two. Most of the money just goes to money-processing companies, and it causes tax problems for me. Thank you!
FUNCTIONAL PROGRAMMING!
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.”
JUST $10 FREE!
Because of my desire to make learning functional programming as affordable as possible for everyone, this PDF is now free!
(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.)
