To get the most out of this book

Readers will make the best use of this book if they first read the chapter and execute the code file associated with that chapter. Further knowledge may be acquired if readers go through the entire template, trying to understand the importance of each and every line of JSON code in each template. Finally, I would recommend that readers write these templates on their own at least once, so as to really develop complete hands-on knowledge of the subject. While doing so, you can refer to these templates as well.
