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.
Get started now by creating a new collection.
See the example tests.
Sorry for late reply.
Your if statement is wrong. After sorting the array (example) [1,2,3,2,1], it looks like this [1,1, 2, 2, 3]. But your if statement does this:
if ( 1 == 1 && 1 != 2){returns true} (1 == 2 && 1 != 2){returns false} and so on...
JS? It's fixed now.
Why early return? ;-)
