Hello guys! morning and welcome to my new tutorial post on JavaScript, in my previous tutorial we talked about how to implement the JavaScript Boolean Properties with examples. Without wasting much time i will go into what i have in stock for you guys in this tutorial.
In this section of my tutorial, we will be using few examples to demonstrate the usage of the Boolean methods. Make sure you read through carefully for proper understanding and ask questions in areas you don't understand properly.

}
var newBook = new book("Java", "Web design tutorialz", 400);
document.write(newBook.toSource() );
</script>
</body>
</html>
<head>
<title>JavaScript toSource() Method</title>
</head>
<body>
<script type = "text/Javascript
function book(title, publisher, price) {
this.title = title;
this.publisher = publisher;
this.price = price;
}
