Not exactly what I expected, especially great, easy to read JavaScript code

In the first part of the book is much to basics. One thinks almost, we can use to skip this part. I recommend it nonetheless, important to carefully read through.
There are given some very general tips, as well as very precise problems and described their solution and implementation.
The most beautiful, it is understandable and clean JavaScript code (within the meaning of "Clean Code"). Thus, like "UrlEngine" is again as a class name instead of "u".

Otherwise, as a Apress book is written. Pro chapter there is an introduction, then the problem with the solution and then finally a summary.

The English is simple, formal and written loosely to the appropriate places :-).
