It works just fine in Chrome's DevTools.

  > dividers[2](6)
  3
  > dividers[undefined](6, 3)
  2

The code uses dividers[divisor] so dividers[3](6, 3) so undefined(6,3) and that does not work

Oh, yeah the divideSomeNumbers() function doesn't work correctly. It should probably be using:

  var divider = dividers[divisor] || dividers[undefined];
