JavaScript has grown in popularity and is destined to remain the language of the web for years to come. It's made into other languages such as PHP and most recently is found in Chrome. Initially designers and non programmers were attracted to JavaScript. As it's matured it has become a programmer's tool too. This book identifies key problem areas for Web developers face when working with JavaScript and offers solutions in the form of coding patterns and design patterns. In addition to codifying the problems and solutions, Stoyan Stefanov offers practical advice and examples showing patterns implemented. Along the way, he points out common anti patterns - solutions that cause more harm than good.
