I kind of stumbled to get to this solution. It's much easier to code alone than having someone on the other side, so keep that in mind when you interview.

var romanToDecimal = function (n) {
	
	var table = {
			I : 1,
			V : 5,
			X : 10,
			L : 50,
			C : 100,
			D : 500,
			M : 1000
		},
		value = 0,
		current,
		next,
		i, j;
		
	for (i = 0, j = n.length; i  current ? -1 : 1);
	}
	
	return value;
}
