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.

Understanding design patterns

One of the most relevant books in software engineering was Design Patterns: Elements of Reusable Object-Oriented Software, 1994, written by the Gang of Four (GOF): Erich Gamma, Richard Helm, Ralph Johnson, and John Vlissides. This book presented about two dozen different OOP patterns and has been recognized as a highly important book in computer science.

Patterns are actually a concept from architectural design, originally defined by an architect, Christopher Alexander.

In software terms, a design pattern is a generally applicable, reusable solution to a commonly-seen problem in software design. Rather than a specific finished and coded design, it's a description of a solution (the word template is also used) that can solve a given problem that appears in many contexts. Given their advantages, design patterns are on their...
