Your goal:
Clobber window.domc
The first thing you can do with DOM Clobbering is adding arbitrary new
properties to the window object, which is the goal of this
challenge. The window object can be clobbered by most
elements, however you cannot override existing properties. To clobber, you
need to be able to insert an element into the DOM with the correct
name or id attribute. Note that the attribute
depends on the element you select.
