JavaScript is most often used in a browser on the client side. It is a scripting language that can make vanilla HTML pages more interactive. By now it, like HTML, is very stable. And if you design web pages, it is a good addition to your skill set. Being stable and popular means that there is no shortage of books on it. So on what basis should you prefer this book?
Well, it takes its title very literally. The pedagogy really does emphasise copious examples. In a typical chapter, the examples take up over half the space. Plus each chapter includes a problem set. Yay! You need to learn by doing. Yet so many computer books omit this. Granted, some topics require so many parts to interoperate that writing problems is nontrivial. But to test JavaScript code, all you need is a browser, text editor and a web server. These days, all computers have the first two items. And, in the context of you wanting to learn JavaScript, you DO have a web server that you can load files onto, don't you?
My only quibble is that I wish there were more problems in each chapter. This could take up very little extra room, say a page per chapter. But it would roughly triple the number of problems, and give the reader an even more exhaustive exploration of the topics.
