Preface

It is now a fact that JavaScript is the most widely used language in the world. Born as a simple glue between the user and the HTML, it has evolved over the years and has acquired an increasingly important role. Today, its scope is no longer just the Web browser, but it lives also on the server, on the desktop PC, on mobile devices up to embedded devices. JavaScript is no longer a simple language to write some scripts, but a language to create complex applications.

Unfortunately, many believe that JavaScript cannot compete with programming languages such as C ++, Java or C #. Many developers with a traditional OOP background think that JavaScript does not have the characteristics to be considered a true Object-Oriented language. This book aims to disprove this prejudice and to show that JavaScript has the characteristics to be considered a true OOP language, although with its peculiarities that make it unique. Thanks to the latest innovations introduced by the ECMAScript standard, we will see how we can write robust and efficient code with JavaScript and we can apply those typical principles of Object-Oriented Programming to create scalable and maintainable applications.
