Tell us what’s happening:

Hi, so here I have tested all the provided examples, and it seems that there is nothing wrong with the algorithm, but I’m still not passing this challenge? I tried also concatenating, directly slice arr1 as a whole to paste, the results are all fine, but failed to pass just the same. can someone help me?

Your code so far


function frankenSplice(arr1, arr2, n) {
  let result = arr2.slice();
  for(let i = 0; i < arr1.length; i++){
    result.splice(n, 0, arr1[i]);
    n++;
  }
  console.log(result)
  return arr2;
}

frankenSplice([1, 2, 3], [4, 5, 6], 1);
