Mastering Dojo JavaScript and Ajax Tools for Great Web Experiences~tqw~_darksiderg.pdf

What readers are saying about Mastering Dojo

I’m so glad to see this book released. Dojo has a lot of power, but

there’s also a lot of complexity to knowing which API methods to use

when, and how to use them, and this book goes beyond just explain-

ing the Dojo API to explaining what developers need to know to use it

effectively.

Mastering Dojo will teach you how to build an Internet application

that will impress your end users and delight you while you’re writing

it. The book also explains Dojo’s JavaScript underpinnings, both for

newcomers and for refugees from other languages.

Ian Dees

Software engineer

The book really rolls out the red carpet for Dojo to emerge with guns

blazing! The authors show you how easy it is to use impressive

widgets without installing a thing. I was amazed to discover that

JavaScript is not just a toy language, how Dojo is built on top of it,

and how both are invaluable in any web development project. Buy

this book. It’s the next best thing to having the authors working at

your side.

Mastering Dojo is an understandable, in-depth guide to learning the

Dojo Toolkit. It’s a great supplement to the Dojo Toolkit’s online docu-

mentation.
