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.

The difference is the first code won't reach
array[array.length]
that'sundefined
because it'll return earlier. Also the second won't work for other reasons, but that's the main difference.This comment is hidden because it contains spoiler information about the solution
Why are you returning an array?
The at() function is in Node versions 16.6.0 and above, which codewars doesn't have
my code returns the right numbers, but the codewars platform is saying at() is not a function
what gives?
