jQuery is the closest thing JavaScript has to a standard library, yet many programmers never venture beyond its most obvious facilities. As well as having easy to use and very powerful DOM manipulation features, described in the companion book Just jQuery: The Core UI, it also offers an improved JavaScript event system, help with writing asynchronous code in the form of Promises, and easy to use and powerful AJAX functions.
Written for JavaScript developers working with advanced web pages Just jQuery: Events, Async & AJAX covers the parts of jQuery not associated with the DOM. Specifically it is about how to make use of jQuery's event functions, Deferred and Promise functions and its AJAX functions. While not every programmer will need these advanced features in the early stages of using JavaScript, they are unavoidable aspects of modern web programming and sooner or later you will find a need to master them all.
This book is about ideas. It does show you how to use jQuery, but mainly by explaining how jQuery approaches the task. Once you understand this there is little need to go over complicated examples where the problem is seeing the big ideas because the small detail is overwhelming. This is not a book of projects or case studies, it is about understanding jQuery.
