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.

interface and the game's functionalities, we will be needing JavaScript. We will need the following JavaScript files in the scripts folder: app.main.jsapp.display_functions.jsapp.init.jsapp.key_handler.jsapp.movement_functions.jsapp.constants.js The app.main.js file Our app.main.js file should contain the following function that will deal with the app.key_handler.js file and your computer's keyboard. It will also call the app.init.js file for the initialization of our variables. Note Here we
this.right = true; this.left = false; } else { this.direction = APP.Direction.STOP; } } if (this.down) { if (APP.map.marks[this.y + 1][this.x] !== APP.WALL_MARK) { this.up = false; this.down = true; this.right = false; this.left = false; } else { this.direction = APP.Direction.STOP; } } if (this.left) { if (APP.map.marks[this.y][this.x - 1] !== APP.WALL_MARK) { this.up = false; this.down = false; this.right = false; this.left = true; } else { this.direction = APP.Direction.STOP; } } }; The

Variables We already know that the computer world has nothing but data. There are different types of data (we call them data types), as follows: Your name is a kind of dataYour age is dataYour grade is also data Yet, they all are different. What is the difference between them? Your name only contains a group of characters or, as some people also
does the website contain? A few web pages? You may see some text, few images, one or two text fields, buttons, and some more elements on each of the web pages. Each of these elements are formatted by HTML. Let me introduce you to a web page. On your Internet browser, go to https://www.google.com.
