Tell us what’s happening:
This is the method I came up with.But I don’t know how to edit a new solution for this topic.

Your code so far

function frankenSplice(arr1, arr2, n) {
  // It's alive. It's alive!
  return arr2.slice(0,n).concat(arr1).concat(arr2.slice(n));

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