modules.

Examining Dojo Core

Now that you’ve gotten a foot in the Dojo, it’s time to back up a little and take a closer look at what Dojo

core offers to a JavaScript developer. The other aspects touched upon in the initial sample will return

throughout the rest of this part of the book.

Declaring, Loading, and Providing Dependencies

Deﬁning modules, declaring dependencies, and dynamically loading code is a key facet of Dojo. What’s

especially nice, though, is that you can use these facilities in your own projects.

Using dojo.require() to Declare and Load Dependencies

You’ve already seen part of this system in action with

dojo.require()

, used like so:

dojo.require("dojo.parser");
