Chapter 1: Enhancing Development with Dojo Core

The

dojo.require()

calls you see in this

block use the Dojo module system. For each of these,

if the named module has not already been loaded, the Dojo core attempts to locate and load it dynami-

cally to satisfy each dependency. If any of these modules declares further requirements — and these, in

particular, do — Dojo will scoop them up as well.

In fact, if you happen to use Firefox as your browser, and have the Firebug extension installed, you

can take a look at the network activity tab and monitor all the requests generated by the requirements

speciﬁed. Check out Figure 1-1 for an example of what you might see. There’s quite a lot going on here,

but keep in mind that there are tools for optimizing this later on.
