general queries regarding native properties!!
Are Native Properties of any object the same as properties in HTML DOM?
If yes, then how to know all the methods/properties available in case if it is native object ? (from MSDN or any other source)
For example, there is a currentStyle object which is native and we can use it to find font, color, background color etc
Object Spy list down all the native properties and you may access it in script via DOM.
