Functional Programming in Kotlin is a reworked version of the bestselling Functional Programming in Scala, with all code samples, instructions, and exercises translated into the powerful Kotlin language. In this authoritative guide, you’ll take on the challenge of learning functional programming from first principles, and start writing Kotlin code that’s easier to read, easier to reuse, better for concurrency, and less prone to bugs and errors.
about the technology
Kotlin is a new JVM language designed to interoperate with Java and offer an improved developer experience for creating new applications. It’s already a top choice for writing web services, and Android apps. Although it preserves Java’s OO roots, Kotlin really shines when you adopt a functional programming mindset. By learning the core principles and practices of functional programming outlined in this book, you’ll start writing code that’s easier to read, easier to test and reuse, better for concurrency, and less prone to bugs.
about the book
Functional Programming in Kotlin is a serious tutorial for programmers looking to learn FP and apply it to the everyday business of coding. Based on the bestselling Functional Programming in Scala, this book guides intermediate Java and Kotlin programmers from basic techniques to advanced topics in a logical, concise, and clear progression. In it, you'll find concrete examples and exercises that open up the world of functional programming. The book will deliver practical mastery of FP using Kotlin and a valuable perspective on program design that you can apply to other languages.

I was unable to find a resource other than this book that gathers these topics in a both concise and complete text.
A great overview of functional programming, building up from the beginning. The kind of book you can keep getting more and more out of over time.
This is a fantastic book if you want to finally get what's the fuss about FP.
One of best books I have read about the concepts and techniques of functional programming with my favorite programming language Kotlin.
The best reference to formalize and introduce functional programming as a branching of Algebra. There is enough mathematical formalism to frame correctly the methods, but also a pragmatic approach to programming.
About every chapter had an "aha!" a moment. I've frequently found principles that I'd use in OOP too.
Even though the text was not loaded with traditional FP jargon (such as "monad"), it did a great job of paving the way to understanding those ideas.
