jQuery.unique on an array of strings

Question

The description of jQuery.unique() states:

Sorts an array of DOM elements, in place, with the duplicates removed. Note that this only works on arrays

Answer 1

$.unique will remove duplicate DOM elements, not identical DOM elements. When you try to use it on strings, you get unpredictable behavior and the sorting will (probably) fail.

It's a function intended for internal use by jQuery only, and won't be useful to mere mortals like you and I.
