Overview of this book

JavaScript is an object-oriented programming language that is used for website development. Web pages developed today currently follow a paradigm that has three clearly distinguishable parts: content (HTML), presentation (CSS), and behavior (JavaScript). JavaScript is one important pillar in this paradigm, and is responsible for the running of the web pages. This book will take your JavaScript skills to a new level of sophistication and get you prepared for your journey through professional web development. Updated for ES6, this book covers everything you will need to unleash the power of object-oriented programming in JavaScript while building professional web applications. The book begins with the basics of object-oriented programming in JavaScript and then gradually progresses to cover functions, objects, and prototypes, and how these concepts can be used to make your programs cleaner, more maintainable, faster, and compatible with other programs/libraries. By the end of the book, you will have learned how to incorporate object-oriented programming in your web development workflow to build professional JavaScript applications.

Design patterns


The second part of this chapter presents a JavaScript approach to a subset of the design patterns introduced by Design Patterns: Elements of Reusable Object-Oriented Software, an influential book most commonly referred to as the Book of Four, the Gang of Four, or GoF (after its four authors). The patterns discussed in the GoF book are divided into the three following groups:

  • Creational patterns that deal with how objects are created (instantiated)

  • Structural patterns that describe how different objects can be composed in order to provide new functionality

  • Behavioral patterns that describe ways for objects to communicate with each other

There are 23 patterns in the Book of Four, and more patterns have been identified since the book's publication. It's way beyond the scope of this book to discuss all of them, so the remainder of the chapter demonstrates only four, along with examples of their implementation in JavaScript. Remember that the patterns are more about interfaces and...
