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.

Chapter 4. Objects

Now that you've mastered JavaScript's primitive data types, arrays, and functions, it's time to stay true to the promise of the book title and talk about objects.

JavaScript has an eccentric take on the classical Object-oriented programming. Object-oriented programming is one of the most popular programming paradigms and has been a mainstay in most of programming languages like Java and C++. There are well defined ideas proposed by classical OOP that most of these languages adopt. JavaScript, however, has a different take on it. We will look JavaScript's way of supporting OOP.

In this chapter, you will learn the following topics:

  • How to create and use objects

  • What are the constructor functions

  • What types of built-in JavaScript objects exist and what they can do for you
