Slice and Splice/My results are correct but fCC doesn't agree

JavaScript
1

Hi,

I’ve tested the following code, & it produces the correct results. However, the freeCodeCamp program tells me I’m not delivering the correct results. Is this because I’m not supposed to use an array as the 3rd argument in splice?

Thank you for your time,

Michael

function frankenSplice(arr1, arr2, n) {
  let arrResult = arr2.slice()
  arrResult.splice(n, 0, arr1); 
  console.log(arrResult);
  return arrResult;
}

frankenSplice([1, 2, 3], [4, 5, 6], 1);
frankenSplice([1, 2, 3], [4, 5], 1);
frankenSplice([1, 2], [“a”, “b”], 1)
frankenSplice([“claw”, “tentacle”], [“head”, “shoulders”, “knees”, “toes”], 2)

You are returning a multi-dimensional array when you need to return a flat array.

I don’t understand your question.

I was talking about your demo I though Fcc’s editor has a module to execute code now I didn’t see that it was on reply.it
