Definition and Usage
$The .uniqueSort() function searches the array object, sorts the array, and removes any duplicate nodes.
Note:Two different nodes with the same attributes are not considered duplicates. This function only applies to arrays of plain JavaScript DOM elements, mainly for internal jQuery use.
Before jQuery 3.0, this method was called jQuery.unique().
