Preface
As you can guess from the title of the book, this book is designed and set up for kids so that they can teach themselves JavaScript and create some projects using JavaScript.
By abstracting the core web programming in an unparalleled way, JavaScript changed websites and web apps forever. Boring static websites and non-interactive websites have now become quite awesome with the touch of JavaScript. Using JavaScript, you can develop web applications, even smartphone applications too, quickly without compromising quality. You can be very productive and deal with almost no configuration on your hardware and software if you start playing with JavaScript. Please remember that this is not a reference book, but you can learn every basic concepts of JavaScript from it. So, for the kids aged 10 and above, this will be a perfect book to discover the world of JavaScript.
What this book covers
Chapter 1, Exploring JavaScript in the Console, discusses JavaScript and the JavaScript Development Environment, including Google Developer Tools. We will install the necessary software and print a few simple lines of code in this chapter.
Chapter 2, Solving Problems Using JavaScript, covers JavaScript fundamentals from the main syntax to some easy commands in the console. We will learn how variables work and what can be achieved with arithmetic operators. We will also run some simple commands to solve problems inside the console.
Chapter 3, Introducing HTML and CSS, will make real use of JavaScript and will cover HTML, which empowers the readers to make use of JavaScript not only in the console but also in the browser's view. We will also explain the basics of CSS, such as CSS selectors, and CSS layouts.
Chapter 4, Diving a Bit Deeper, covers some of the more advanced features that JavaScript offers. We discuss for and while loops, if statements, and switches-case.
Chapter 5, Ahoy! Sailing into Battle, teaches us how to develop the famous game, Battleship. Building upon what we've learned in the previous chapters, the tiny tots will learn to put this information into use.
Chapter 6, Exploring the Benefits of jQuery, is all about jQuery, a famous JavaScript library, and the advantages of using it.
Chapter 7, Introducing the Canvas, discusses HTML canvas, and we will learn how we can use it on our projects.
Chapter 8, Building Rat-man!, teaches us to develop a famous game, Pac-Man, except there is a rat, some cats, and lots and lots of cheese balls to eat! ;)
Chapter 9, Tidying up Your Code Using OOP, teaches object-oriented programming (OOP) and discusses how JavaScript is an OOP language.
Chapter 10, Possibilities, shows the reader what is possible using the skills they have developed reading this book.
What you need for this book
Throughout this book, we have used Google Chrome as our browser to run our JavaScript code on the console. We wrote our code using Atom, a famous text editor.

Chapter 1. Exploring JavaScript in the Console
Before we start talking about lines of codes, objects, variables, and so on, we need to know what JavaScript is. JavaScript is a programming language that is used to add interactivities to the web pages and build web applications. Static websites are not very popular these days, therefore, we use JavaScript to make our websites interactive.
Some people also call it a scripting language as it is an easy language and does not require compilers like other languages. JavaScript was not designed as a general purpose programming language, it was designed to manipulate web pages. You can write a desktop application using JavaScript. JavaScript can also access your machine's hardware. You can try making a desktop application with a software development kit (SDK) such as PhoneGap for mobile or the Microsoft app SDK for desktop. The JavaScript codes are interpreted on web pages and then run by a browser. Any modern Internet browser, for example Firefox, Safari, Google Chrome, UC Browser, Opera, and so on, supports JavaScript.
Note
A compiler is a computer program that processes codes and turns them to machine language. Making a website interactive means adding features that are controlled by the users to the website. For example, online registration forms, online calculator, and so on. The Static website has fixed objects and contents and it displays the same information to all the visitors.
Basically, JavaScript is included on an HTML page or written on a separate file that has a .js extension. If you know nothing about HTML, don't worry as you will learn about it in Chapter 3, Introducing HTML and CSS. So, where can you use JavaScript?
The answer is simple, you can do the following:
Note
The thing that you should remember is JavaScript is not Java, the programming language developed by Sun Microsystem.
Throughout this book, we will use Google Chrome as the default browser and Atom as the text editor.
If you do not have these two software already installed on your computer, it is necessary to download and install them.
We will use the Atom text editor as it is a cross-platform editor, has a built-in package manager, does smart autocompletion, and has a lot of other advantages.
