Preface

This is the second edition of the highly rated book Object-Oriented JavaScript by Stoyan Stefanov, Packt Publishing. After the release of the first edition, in the last five years, JavaScript has moved from being mostly used in browsers for client-side technologies to being used even on server side. This edition explores the "language side" of JavaScript. The stress is on the standards part of the language. The book talks about ECMA Script, Object-Oriented JS, patterns, prototypal inheritance, and design patterns.

The book doesn't assume any prior knowledge of JavaScript and works from the ground up to give you a thorough understanding of the language. People who know the language will still find it useful and informative. Exercises at the end of the chapters help you assess your understanding.
