Overview of this book

JavaScript is the most widely-used programming language for web development and that's not all! It has evolved over the years and is now being implemented in an array of environments from websites to robotics. Learning JavaScript will help you see the broader picture of web development. This book will take your imagination to new heights by teaching you how to work with JavaScript from scratch. It will introduce you to HTML and CSS to enhance the appearance of your applications. You’ll then use your skills to build on a cool Battleship game! From there, the book will introduce you to jQuery and show you how you can manipulate the DOM. You’ll get to play with some cool stuff using Canvas and will learn how to make use of Canvas to build a game on the lines of Pacman, only a whole lot cooler! Finally, it will show you a few tricks with OOP to make your code clean and will end with a few road maps on areas you can explore further.

Chapter 9. Tidying up Your Code Using OOP

In this chapter, we are going to learn about object-oriented programming (OOP) and discuss the code of the famous game, Hangman.

"OOP is a programming paradigm that uses abstraction to create models based on the real world. OOP uses several techniques from previously established paradigms, including modularity, polymorphism, and encapsulation." or "OOP languages typically are identified through their use of classes to create multiple objects that have the same properties and methods."

You probably have assumed that JavaScript is an object-oriented programming language. Yes, you are absolutely correct. Let's see why it is an OOP language. If a computer programming language has the following few features, we call it object oriented:

  • Inheritance

  • Polymorphism

  • Encapsulation

  • Abstraction

Before going any further, let's discuss objects. We create objects in JavaScript in the following manner:

var person = new Object();
person.name = "Harry Potter";
person.age =...
