• 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.
