We take an opportunity to present this text book on “Elements of Scripting Language” to the students of BSc graduates of the university .Web programming is about more than creating and formatting webpages and websites, though that is often a starting point for many. Using scripting languages such as JavaScript, it becomes possible to add a lot more functionality to a site. This book teaches the essentials of working with the most important web technologies. From client development using HTML and Javascript, through to full server side applications.

 The book uses plain and lucid language to explain fundamentals of the subject. Each chapter is supported with necessary illustrations, practical examples.
