Overview of this book

JavaScript is a high-level, dynamic, untyped, lightweight, and interpreted programming language. Along with HTML and CSS, it is one of the three essential technologies of World Wide Web content production, and is an open source and cross-platform technology. The majority of websites employ JavaScript, and it is well supported by all modern web browsers without plugins. However, the JavaScript landscape has changed dramatically in recent years, and you need to adapt to the new world of JavaScript that people now expect. Mastering modern JavaScript techniques and the toolchain are essential to develop web-scale applications. Mastering JavaScript will be your companion as you master JavaScript and build innovative web applications. To begin with, you will get familiarized with the language constructs and how to make code easy to organize. You will gain a concrete understanding of variable scoping, loops, and best practices on using types and data structures, as well as the coding style and recommended code organization patterns in JavaScript. The book will also teach you how to use arrays and objects as data structures. You will graduate from intermediate-level skills to advanced techniques as you come to understand crucial language concepts and design principles. You will learn about modern libraries and tools so you can write better code. By the end of the book, you will understand how reactive JavaScript is going to be the new paradigm.

Preface

It would seem that everything that needs to be written about JavaScript has been written. Frankly, it is difficult to find a topic related to JavaScript that has not been discussed ad nauseam. However, JavaScript is changing at a rapid pace. ECMAScript 6 has the potential to transform the language and how we code in it. Node.js has already changed the way in which we write servers in JavaScript. Newer ideas such as React and Flux will drive the next iteration of the language. While we spend our time learning the new features, there is no denying that the foundational ideas of JavaScript have to be mastered. These ideas are fundamental and need attention. If you are already an experienced JavaScript developer, you will realize that modern JavaScript is vastly different from the language that most people have known. Modern JavaScript demands a specific stylistic discipline and rigor of thought. Tools are more powerful and slowly becoming an integral part of the development workflow. Though the language seems to be changing, it is built on some very solid and constant ideas. This book emphasizes on these fundamental ideas.

While the book was being written, things kept changing in the JavaScript landscape. Luckily, we were able to include all the important and relevant updates in this book.

Mastering JavaScript provides you with a detailed overview of the language's fundamentals and some of the modern tools and libraries, such as jQuery, Underscore.js, and Jasmine.

We hope that you enjoy this book as much as we enjoyed writing it.
