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.

Loops


In this paragraph, we will learn something interesting called loop.

Consider that you need to print a line 100 times using JavaScript. What you will do?

You can type document.write("The line I want You to Write"); 100 times in your program or you can use loop.

The basic use of loop is to do something more than one time. Say, you need to print all the integers of 1 + 2 + 4 + 6 +…………+100 series upto 100. The calculation is the same, you only need to do it multiple times. In these cases, we use loop.

We will discuss two types of loops, namely for loop and while loop.

The basic structure of the for loop is as follows:

for(starting ; condition ; increment/decrement)
{
  statement
}

The starting parameter is the initialization of your loop. You need to initialize the loop in order to start it. The condition parameter is the key element to control the loop. The increment/decrement parameter defines how your loop will increase/decrease.

Let's see an example. You want to print javascript...
