Slice and Splice - index n problem

Tell us what’s happening:

Please: what am I doing wrong here? The contents of arr1 are being added to the end of arr2, and not at index n, not sure why.

Your code so far

function frankenSplice(arr1, arr2, n) {
  let arr2Copy = []
  arr2Copy.splice(n, 0, arr1.slice())
  return arr2Copy;

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