Slice and Splice (Correct result but still can't pass)

JavaScript
1

Tell us what’s happening:

When I log my values I get the correct results but when I run the test it doesn’t pass. What am I missing here?

Your code so far


function frankenSplice(arr1, arr2, n) {
  // It's alive. It's alive!
  let len = arr1.length -1;
  let copy1 = arr1.slice(0);
  let copy2 = arr2.slice(0);
  let last = arr2.slice(n);
  // console.log(last);
  copy2.splice(n, len, copy1);
  copy2.push(last);
  // console.log(copy2);
  return copy2; 
}

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

You’re splicing an array, not the values from the array. When you console log, it just shows a list of values: try console logging console.log(JSON.stringify(frankenSplice([1, 2, 3], [4, 5, 6], 1))) and you’ll see the issue

Oh wow thanks, I see the issue now. I’m going to have to insert the values one at a time and not just splice the arrays in.
