Customer Reviews

welcome to dojo thru code
"Learning Dojo" gets you up to speed on using DoJo widgets quickly and efficiently. While the book does cover some advanced JavaScript concepts like closures, you should be comfortable with JavaScript before you start out.

The book was well organized. It starts with the basics of how to use the library and widgets. Later on, internationalization, theme and locales are covered. The example of a basic threading error in AJAX was helpful because it showed WHY approaches wouldn't work. I particularly liked the chart in chapter on with the "selling points" of Dojo.

While I did find one font error (page 28), if this is the biggest error I noticed things are in good shape. There was also a bit of wasted space. For example the almost two pages of character codes (listed one at a time) could have been a table to save space. These are just nits though and don't interfere with readability. And the authors does abbreviate code where possible. The examples build on each other so it isn't too overwhelming reading all that code.

Overall, I did learn a lot from the book. The "real world" examples have a good scope to them - a CRUD example is something many people do! And I really liked the unit testing widget. I learned of several sites to bookmark. Finally, Packt gives some money to the open source project when they sell copies of the book - a very neat concept.
