JavaScript : Functional Programming for JavaScript Developers

By: Ved Antani, Simon Timms, Dan Mantyla

Overview of this book

JavaScript is a high-level, dynamic, untyped, lightweight, and interpreted programming language and functional programming is a style that emphasizes and enables smarter code that minimizes complexity and increases modularity. It's a way of writing cleaner code through clever ways of mutating, combining, and using functions. And JavaScript provides an excellent medium for this approach. By learning how to expose JavaScript's true identity as a functional language, we can implement web apps that are more powerful, easier to maintain and more reliable. The java script: Functional Programming for JavaScript Developers course will take you on a journey to show how functional programming when combined with other techniques makes JavaScript programming more efficient. The first module Mastering JavaScript, stress on practical aspects of Javascript development like—Functions and Closures, Runtime debugging techniques, project layout, events and DOM processing, build tools, Object-oriented patterns, isomorphism—everything that a modern Javascript project would need. The second module, Mastering JavaScript Design Patterns - Second Edition, will explore how design patterns can help you improve and organize your JavaScript code. You’ll get to grips with creational, structural, and behavioral patterns as you discover how to put them to work in different scenarios. This updated edition will also delve into reactive design patterns and microservices as they are a growing phenomenon in the world of web development. It will also show you some advanced patterns, including dependency injection and live post processing. The third module, Functional Programming in JavaScript, will help you to write real-world applications by utilizing a wide range of functional techniques and styles. It explores the core concepts of functional programming common to all functional languages, with examples of their use in JavaScript.

Appendix B. Glossary of Terms

This appendix covers some of the important terms that are used in this book:

  • Anonymous function: A function that has no name and is not bound to any variables. It is also known as a Lambda Expression.
  • Callback: A function that can be passed to another function to be used in a later event.
  • Category: In terms of Category Theory, a category is a collection of objects of the same type. In JavaScript, a category can be an array or object that contains objects that are all explicitly declared as numbers, strings, Booleans, dates, objects, and so on.
  • Category Theory: A concept that organizes mathematical structures into collections of objects and operations on those objects. The data types and functions used in computer programs form the categories used in this book.
  • Closure: An environment such that functions defined within it can access local variables that are not available outside it.
  • Coupling: The degree to which each program module relies on each of the...
