This book is really interesting for both novice and skilled developer to learn the fastest, easiest way to master the term "design pattern" in computer science.
Compared to some of the books I read years ago about design patterns in C++, this book was actually fun to read while at same time has good depth on the topic. Great concept and approach for the purpose of self-study.
As I have just started reading this book, this will be too early to say anything about the book. !! but at a first GLANCE i found it very USER FRIENDLY.
