Mechanics

NinjaScript is designed to be pretty easy to read, but a brief overview of how
it works can aid in understanding.

Basically, NinjaScript is built around an event binding engine. As nodes are
added to the DOM that match the selectors provided, the transform functions are
run and event handlers are attached to the nodes as appropriate.

We use DOM mutation events to do trigger the binding, which covers most of the
browsers out there, as well as a homebrewed event that is raised explicitly for
certain dopey browsers (the obvious one) by the NinjaScript machinery.

The upshot is that event handling is much more efficient than delegation, plus
we get element transformation along with, so it’s a win all around.
