Preface

Functional programming is a style that emphasizes and enables the writing of smarter code, which minimizes complexity and increases modularity. It's a way of writing cleaner code through clever ways of mutating, combining, and using functions. JavaScript provides an excellent medium for this approach. JavaScript, the Internet's scripting language, is actually a functional language at heart. By learning how to expose its true identity as a functional language, we can implement web applications that are powerful, easier to maintain, and more reliable. By doing this, JavaScript's odd quirks and pitfalls will suddenly become clear and the language as a whole will make infinitely more sense. Learning how to use functional programming will make you a better programmer for life.

This book is a guide for both new and experienced JavaScript developers who are interested in learning functional programming. With a focus on the progression of functional programming techniques, styles, and detailed information about JavaScript libraries, this book will help you to write smarter code and become a better programmer.
