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.

Simple and readable
thanks for your advice, i will take it into consideration next time
Splicing the parameter will modify the original array which might cause code to break elsewhere.
Best approach here to avoid that is to clone items. If it is a shallow array like so:
const itemsClone = [...items];
