    Is it possible that an argument could be added here to specify to use hasOwnProperty() ? I initially assumed that hasOwnProperty would be taken into account here.

    This function does the same thing?

    function isempty(object){
    return (object.length > 0 ? true : false);
    }
  • No. That would work on arrays, but objects don't have a length property (by default).
