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.

Explaining the code


Now, let's discuss the code that we previously used. We used the following function in our code:

jQuery(document).ready(function(){
//our codes. 
});

This is a jQuery function that allows you to set your jQuery ready to be used. You can replace jQuery with a dollar sign ($) as shown in the following:

$(document).ready(function(){
//our codes.
});

You need to think where you want to apply jQuery. We have written <h1>Click Here!</h1> in our body tags. We wanted our Click Here! to do something when clicked and that's why we added a click function similar to the following format:

  jQuery('h1').click(function(){
    //our codes.
  });

The jQuery can be replaced with $ as earlier mentioned.

We added an alert function so that when we click on our text, there appears an alert box.
