Slice and Splice Semantic problem

Tell us what’s happening:
I am getting the correct output.But my solution does not pass the test cases

Your code so far

function frankenSplice(arr1, arr2, n) {
  // It's alive. It's alive!
  let t = arr2.slice(0);
  return t;

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