About the Book
This book explores the core principles of functional programming (FP) as they are applied to JavaScript. But what makes this book different is that we approach these principles without drowning in all the heavy terminology. We look at a subset of FP foundational concepts that I call "Functional-Light Programming" (FLP) and apply it to JavaScript.

Software Developer
By focusing on the principles instead of terminology I now feel much more confident in my understanding of the foundation of functional programming. I'm motivated and excited to dive even deeper!
Islam Attrash
JS Engineer
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!

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.
