Array2 is not iterable

There’s an error when I’m pressing the attempt button:
TypeError: array2 is not iterable
However, when I press the test button, it works fine. Why is that?

my code:

function comp(array1, array2) {
  let newSecondArr = [];
  for (let elements of array2) {
    newSecondArr.push(Math.sqrt(elements))
  }
  return array1.sort((a, b) => a - b).join(',')
    === newSecondArr.sort((a, b) => a - b).join(',')
}

Thank you for the reply. I edited my post :slight_smile:

check the remarks in the kata description - are you always given arrays?

It worked!

I added an if statement: if (array1 !== null && array2 !== null) and I changed the for…of loop to this: for (let i = 0; i < array2.length; i++)

Thanks!
