A Skeptic's Guide to Functional Programming with JavaScript

What if the team hates my functional code? Learning functional programming can be intoxicating. Your code becomes more elegant, more expressive-solid. But what if the people you work with don't get it? Some of their concerns are legitimate. Others are plain ignorant. But how do you tell the difference? And either way, how do you have a rational conversation when there's so much angst? It seems like an impossible situation. But it doesn't have to be. What if you knew what to expect, ahead of time? Imagine if you already had intelligent, thoughtful responses, ready to go. Better yet, what if you could bring the team on the journey with you; help them see the beauty and benefits of functional code? This book will guide you through sorting myths from reality. Learn to spot performance pitfalls. Adjust your code to suit the team's familiarity, without compromising confidence. Learn to have nuanced, reasonable discussions. Write expressive, elegant code... and ship it!

Mastering JavaScript Functional Programming

Master Functional Programming techniques with this comprehensive guide for writing cleaner, safer, high-performing JavaScript codes About This Book Become proficient and skilled with Functional Programming in JavaScript to solve real-world development problems Successfully apply Functional Programming concepts and techniques to everyday JavaScript programming Bring modularity, reusability, testability, and performance to your web apps Who This Book Is For If you are a JavaScript developer and want to apply functional programming techniques, then this book is for you. Only a basic knowledge of the concepts of functional programming is required for this book. What You Will Learn Create more reliable code with closures and immutable data Convert existing methods into pure functions, and loops into recursive methods Develop more powerful applications with currying and function composition Separate the logic of your system from implementation details Implement composition and chaining techniques to simplify coding Use functional programming techniques where it makes the most sense In Detail Functional programming is a programming paradigm for developing software using functions. Learning to use functional programming is a good way to write more concise code, with greater concurrency and performance. The JavaScript language is particularly suited to functional programming. This book provides comprehensive coverage of the major topics in functional programming with JavaScript to produce shorter, clearer, and testable programs. You'll delve into functional programming; including writing and testing pure functions, reducing side-effects, and other features to make your applications functional in nature. Specifically, we'll explore techniques to simplify coding, apply recursion for loopless coding, learn ways to achieve immutability, implement design patterns, and work with data types. By the end of this book, you'll have developed the JavaScript skills you need to program functional applications with confidence. Style and approach This book takes an easy-to-follow, step-by-step tutorial approach. You will make the most of JavaScript programming with a focus on the progression of functional programming techniques, styles, and detailed information about JavaScript libraries.
