JavaScript Projects for Kids

By: Syed Omar Faruk Towaha

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.

Inheritance in JavaScript

To inherit means derive something (such as, characteristics, quality, and so on) from one's parents or ancestors. In programming languages, when a class or object is based on another class or object in order to maintain the same behavior of the parent class or object is known as inheritance.

We can also say that this is a concept of gaining properties or behaviors of something else.

Suppose, X inherits something from Y; it is like X is a type of Y.

JavaScript occupies the inheritance capability. Let's take a look at an example. A bird inherits from an animal as a bird is a type of animal. Therefore, a bird can do the same thing that an animal does.

This kind of relationship in JavaScript is a little complex and needs a syntax. We need to use a special object called prototype, which assigns the properties to a type. We need to remember that only function has prototypes. Our Animal function should look similar to the following:

function Animal(){
//We can code here.
