Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.

This not issue the given function mentions array as Number[] so u can change to any[]
This comment is hidden because it contains spoiler information about the solution
It's return it (the array without duplicate), not return them (the duplicates). And nowhere it says you should create a new array with them. You also have a couple of examples in the description if you have any doubt.
the question is not clear , it says: function that removes duplicates from an array of non negative numbers and returns it as a result.
so what is thought is that i need to return the douplicates items in a new list, but it turned out that it requires to return the same array after removing douplicates!
kindly clarify the question to be like:
function that returns array of non negative numbers without douplicate
