This book has delivered exactly what I was hoping for, an in-depth look into modern day JavaScript. I rarely use JavaScript nowadays in my day to day job. I have been lucky to avoid the messy browser applications it is usually a part of the past few years. That was my primary reason for buying the book. Although I may not like it, JavaScript is here to stay, and I need to keep current with it. The book is broken into 4 parts. Core JavaScript, Client-Side JavaScript, Core JavaScript Reference, and Client-Side JavaScript Reference. The book has chapters on Lexical Structure, Expressions and Operators, Statements, Objects, Arrays, Functions, Classes and Modules, Pattern Matching with Regular Expressions, JavaScript Subsets and Extensions, Server-Side JavaScript, JavaScript in Web Browsers, The Window Object, Scripting Documents, Scripting CSS, Handling Events, Scripted HTTP, The jQuery Library, Client-Side Storage, Scripted Media and Graphics, HTML5 APIs, and then continues on with the Core JavaScript Reference and the Client-Side JavaScript Reference. The downloadable code is very well organized and usable. All the code in the book, and there is a ton of it, is available. The book is very well written and makes for a really good read as well as a great reference. It is in depth and very thorough. All in all I think this a great book. It will be on my desk for the next few years until I need to replace it with the 8th or 9th version. If you are a web developer, you need this book by your side.
