Mastering JavaScript Functional Programming - Second Edition

By: Federico Kereki

Overview of this book

Functional programming is a paradigm for developing software with better performance. It helps you write concise and testable code. To help you take your programming skills to the next level, this comprehensive book will assist you in harnessing the capabilities of functional programming with JavaScript and writing highly maintainable and testable web and server apps using functional JavaScript. This second edition is updated and improved to cover features such as transducers, lenses, prisms and various other concepts to help you write efficient programs. By focusing on functional programming, you’ll not only start to write but also to test pure functions, and reduce side effects. The book also specifically allows you to discover techniques for simplifying code and applying recursion for loopless coding. Gradually, you’ll understand how to achieve immutability, implement design patterns, and work with data types for your application, before going on to learn functional reactive programming to handle complex events in your app. Finally, the book will take you through the design patterns that are relevant to functional programming. By the end of this book, you’ll have developed your JavaScript skills and have gained knowledge of the essential functional programming techniques to program effectively.

In this chapter, we have made a bridge from the OO way of thinking and the usual patterns that we use when coding that way, to the FP style, by showing how we can solve the same basic problems (but rather more easily) than with classes and objects. We have seen several common design patterns, and we've seen that the same concepts apply in FP, even if implementations may vary, so now you have a way to apply those well-known solution structures to your JavaScript coding.

In Chapter 12, Building Better Containers – Functional Data Types, we will be working with a potpourri of functional programming concepts, which will give you even more ideas about tools you can use. I promised that this book wouldn't become deeply theoretical, but rather more practical, and we'll try to keep it this way, even if some of the presented concepts...
