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.

i sometimes get a [Function] object, wich is annoying and i had to filter out with Number.isInteger(arr[x])
Does anyone know why this is happening?
Edit: This only happened in the random tests
