Functional-Light JavaScript: Pragmatic, Balanced FP in JavaScript Kindle Edition

by Kyle Simpson (Author), Brian MacDonald (Editor), Brian Lonsdorf (Editor, Foreword), Format: Kindle Edition
4.6 out of 5 stars (89)
Functional-Light JavaScript is a balanced, pragmatic exploration of Functional Programming in JavaScript.

Functional Programming (FP) is an incredibly powerful paradigm for structuring code that yields more robust, verifiable, and readable programs. If you've ever tried to learn FP but struggled with terms like "monad", mathematical concepts like category theory, or symbols like λ, you're not alone.

Functional-Light programming distills the most vital aspects of FP—function purity, value immutability, composition, and more!—down to approachable JavaScript patterns. Rather than the all-or-nothing dogmatism often encountered in FP, this book teaches you how to improve your programs line by line.

Editorial Reviews

Review

"By focusing on principles instead of terminology, I now feel much more confident in my understanding of foundations of functional programming. I'm motivated and excited to dive even deeper!" --Hannes Lund, Software Developer


"I can say for sure that the FLJS book is mind-blowing! I almost lost my mind with the concepts it explains! This book gave me the right way of programming by understanding concepts more than focusing on Frameworks!" --Islam Attrash, JS Engineer


"Nobody explains JavaScript as well as Kyle Simpson. He is as thorough as he is humble, explaining complex ideas in simple language. Kyle makes learning JavaScript easy without skipping the details." --Dmitri Wolf, Front End Developer, IBM


"After reading this book, I finally found the reason why I should use functional programming. Although I'm experienced in using list operators, chapter 9 gave me a new point of view to use them better. I would recommend this book to my coworkers." --Tuyen Ho, Full-Stack Developer, Grande JSC

    2.0 out of 5 stars OK at best. Kyle can do much better
    Reviewed in the United Kingdom on September 10, 2018
    Format: PaperbackVerified Purchase
    Very disappointed with this book. Kyle is a very knowledgable individual with excellent JavaScript insight. His free books about "You don't know JS" are a fantastic resource which every front-end developer should read. I already know alot about FP (Functional Programming) but after reading this entire book, there is was not much to take away from this book. It is clear Kyle enjoys FP but not sure what the purpose of the book is. It contains plenty of code snippets but nothing to show the power and the brain-bending thought process which it sometimes requires.

    I would recommend reading some free introductions to FP online and learn the "proper" way without the confusion produced by this book. You might want to really learn ES6 (destructing, rest, spread and array methods) and truly understand JavaScript and all of its quirks.
