thank you so much

You skipped that line in the description:

This array should only include the numbers in the loop, not any that lead into the loop

Please use the question tag to ask for help in the future ;-)

Can someone tell me why my solution is not passing all test cases?

function isHappy(n, pow) {
  const cachedValues = [n]
  while (true) {
    const digits = n.toString().split("").map(Number)
    let total = 0
    for (let i = 0; i < digits.length; i++) {
      total += Math.pow(digits[i], pow)
    }

    if (total === 1) {
      return [1]
    }

    if (cachedValues.includes(total)) {
      cachedValues.push(total)
      return cachedValues
    }

    n = total
    cachedValues.push(total)
  }
}

Approved

python new test framework is required. updated in this fork

This is an issue.

(By the way, your proposed compareObjects is bug-ridden.)

The description of this kata is completely incomprehensible. What are we supposed to do here?

4^2 + 9^2

Ruby 3.0 should be enabled.

Cool

As it is only 81% kata i think i will extend description. If n is a huppy number then return [1]; If not, then return only "repeating numbers". And repeating numbers are the clue to sort out "This array should only include the numbers in the loop, not any that lead into the loop". Rest is quite easy.

OK, fixed it myself :-)

Something wrong with the Ruby checker function, as I received the following error multiple times:

STDERR:

Too many recursions?
