JavaScript emerged as a quick fix language, but in the last decade, it has embedded and closely integrated itself with the web. It is difficult to avoid JavaScript while working with dynamic web content. Due to its prevalence, it was soon accepted as a general-purpose language for working in both client- and server-side programming. The popularity, ease of use and rapid adoption of JavaScript made imperative for us to discuss it for novice as well as experienced users. This book aims at covering the JavaScript language basics and fundamentals to help readers strengthen their programming. It is designed to explain the language in the simplest possible words with a comprehensive hands-on approach toward learning by practice. Every chapter in the book is supplemented with demo code, which will compel you to practically test what you read in the chapters. These live exercises allow easier learning for readers by switching swiftly between theory and practice. Lastly, we provide extended case studies that aim to assist readers in exploring more dimensions of JavaScript as a language. There is so much you can cover in a book, right? With that said, we hope that this book offers you an amazing experience at hands-on learning, and you can come back to it whenever you need a little refreshment.

Writing a book resembles a marathon. It is a long and tedious process. This work would not have been the way it is if not for the support provided by two very special individuals.

A special thanks to Dibyasom Puhan, Undergraduate student at School of Computer Science, University of Petroleum and Energy Studies, Dehradun for his untiring support in developing hands-on code and flawless execution of work. Dibyasom is always a dedicated and sincere individual to trust upon.

Other big thanks go to Kamakshi Negi for her contribution and support throughout the writing of this book. Many times, it is hard to move on. In those moments, she gave us light and never hesitated to step in and contribute to this work. We are humbled to have Dibyasom and Kamakshi with us. We wish them joy, success, and warmth wherever they go in the future. Needless to say, we are always a phone call away.
