JavaScript testing for empty array, object keys

	Javascript testing for empty (undefined) object or array

	This is the problem, for JS object keys and for array's, not that I like really testing for undefined, I would rather set false or true and test for that, but ...;

	var obj = { key: undefined };
	obj["key"] != undefined // false, but the key exists!

	and also;

	if (urlobject[3] == 'undefined') {} // again does not work as expected
