Remove duplicate elements from array in Ruby

I have a Ruby array which contains duplicate elements.

array = [1,2,2,1,4,4,5,6,7,8,5,6]

How can I remove all the duplicate elements from this array while retaining all unique elements without using for-loops and iteration?

array = array.uniq

uniq removes all duplicate elements and retains all unique elements in the array.

This is one of many beauties of the Ruby language.
