Be warned that $.map() is designed to work on a sequence of DOM
elements. Although it would work with other values too, callback
results are not handled as you probably expect: null and undefined
values are discarded and arrays are merged to the final array.
In your case an classic for(key in obj) would be more appropriate, I
think.
