And even though Base and Core are two substantial components of the toolkit, there's also Dijit, DojoX and Util, which easily could span entire articles and books of their own. In short, Dijit is a huge infrastructure of DHTML¬based turnkey widgets. DojoX is a collection of specialised sub-projects ranging from wrappers around Google Gears to graphics functions that can use scalable vector graphics (SVG) to draw in the browser natively.

Util provides DOH, a unit-testing framework and a collection of build tools for squeezing as much performance as possible out of your JavaScript. Although not covered in this article, these topics are well worth investigating and are just as important to your development efforts as Base and Core.
