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.
Danke you for the clarification
We're playing the code golf (https://en.wikipedia.org/wiki/Code_golf) game, tl;dr write a solution with the minimal number of characters. Yes, in real, production code, you'd use
constorlet(varis still valid, but most modern code usesletunlessvaris absolutely necessary, since it has slightly different behavior https://stackoverflow.com/a/11444416/12101554), but this is still valid JavaScript.Use const, let or var!!!
Approved ;-)
Added

Needs random tests
The comments in the initial code needs to be removed ;-)
Overly complicated. :)))))
