Hi there, afaik "Array" is inherited from "Object" that way, that there are only some convenient functions around "Object", but the array is build up with "key-value"-pairs just like an "Object-children list" is too. So "length" just returns the key with the highest value +1.
a = new Object; a.foo = "bla"; a["foo"] -> "bla"; b = new Array; b[0] = "blabla"; b["0"] -> "blabla"; I think the only problem with the Object of the inputNumber[] inputs is, that it should be created like an array. But it is created like a structure. So we are actually dealing with a structure when we accessing a certain value of the inputNumber-"Array".
