returns?? not in the Javascript way.

You probably mean: A[A.length-1] > B[B.length-1]

However this wil not work for:

var A = [1,5,3];
var B = [1,2,3];

================================

I would prefer a 3-way return,
speed-optimized for [large] inequality:

// If A>B return 1, A=B return 0, A<B return -1

function arrTriCompare(A,B) {
  var len = A.length, temp = len - B.length, i;
  if (temp)
    return Math.sign(temp);
  for (i = len-1; i >= 0; i--) 
    if (temp = A[i] - B[i]) 
      return Math.sign(temp);
  return 0;
};
