Query: This is a begining/intermidate level book

The problem with this book is that it is different from the regular series of the visual books.If you know javascipt like I do, this book makes sense. However, if you are new to javascript don't buy this. The explanations are terrible.There are woking examples. The example are the best features of the books because of the simple coding.
