## Definition and Usage
The _$.uniqueSort()_ function sorts an array and removes any duplicate nodes by searching the array object.
**Note:** Two different nodes with the same attributes are considered not duplicates. This function is mainly used internally by jQuery and only applies to arrays of plain JavaScript DOM elements.
Before jQuery 3.0, this method was called jQuery.unique().
