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.
That does work and is quite a bit nicer, but the original problem statement said to create a copy of the array. That's a pretty pointless condition that doesn't even get tested though, so the default arguments should probably be used in a slightly tweaked better version of this Kumite.
You can use
function insertionSort(arr, i = 1, j = 1)
and you would be skipping the first if.
