This is not a reference guide nor a in-depth deep dive into Dojo as the title suggests. Its for people who are beginners to Dojo and even Javascript. The book barely scratches the surface of Dojo and just introduces Dojo concepts and main methods. There is a chapter in the end called Real world Dojo but its still a book for beginners. Once, you are done with this book you probably want to go for Dojo: Definitive Guide or some reference book on Dojo.
