Deleting duplicates from an array of arrays

First question so I apologize for the format.
I was just curious to know as to how can you delete duplicates from an array that consists of arrays. Looking for the code in javascript

For e.g
[[ 1, 1, 1 ], [ 1, 1, 1 ], [ 1, 1, 1 ], [ 1, 2, 3 ]]

The result should be [[ 1, 1, 1] , [ 1, 2, 3]]

I do know how to remove duplicates from a simple array of values (strings or numbers)
