When I define an array var a = {}; a[0] = "hello";
and I print out a.length, I get undefined.
When I define an array var b = new Array(); b[0] = "there";
and print b.length, I get 1.
When I do it the second way, the compiler yells at me for not using the preferred way of defining objects.
In both cases, the arrays hold objects ok, but in the first case, I cannot determine the length of the array.

Hi Shawn, I think it's should be
var a = [];instead of
var a = {}
