The above code does not work. Replace arr with accumulator.

//do the same thing as the Perl "keys" subroutine keys : function (o) { var accumulator = []; for (var propertyName in o) { accumulator.push(propertyName); } return accumulator; }

//get values instead of keys values : function (o) { var accumulator = []; for (var propertyName in o) { accumulator.push(o[propertyName]); } return accumulator; }
