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.
In case this kata ever gets approved, the tests will have to be rewritten, so closing.
This is a common issue in randomly-generated test cases. To generate a random number using Math.random(), there needs to be a lower bound (included) and an upper bound (excluded). However, since numbers in JS are doubles, they start losing some precision after a certain point. This will, in very rare cases, cause the upper bound to be included. If you're interested, you can take a look at MDN's explanation here: Math.random() - JavaScript | MDN.
