Answer 1

In your operation in your initial question, you are performing the following operation:

item1.attr - item2.attr

So, assuming those are numbers (i.e. item1.attr = "1", item2.attr = "2") You still may use the "===" operator (or other strict evaluators) provided that you ensure type. The following should work:

return parseInt(item1.attr) - parseInt(item2.attr);

If they are alphaNumeric, then do use localCompare().
