Need help with the challenge "Slice and Splice"

JavaScript
#1

I’m stuck on the challenge “Slice and Splice”. This code works, but for some reason, FCC isn’t registering it as correct.


function frankenSplice(arr1, arr2, n)
{
  let arrTemp = arr2.slice(0);
  arrTemp.splice(n, 0, arr1);
  return arrTemp;
}

console.log(frankenSplice([1, 2, 3], [4, 5], 1)); //Prints "4,1,2,3,5" to the console

Open the browser console and you will see why it is not working (spoiler: your array has a subarray)

any way to solve this issue. I seem to also have this problem.

function frankenSplice(arr1, arr2, n) {
  
  var arr1Dupe = arr1.slice(0);
  var arr2end = arr2.slice(n);

  var sliced = arr2.slice(0,n);
 
  arr1Dupe.unshift(sliced);
  var nArr = arr1Dupe;

  nArr.push(arr2end);

  return nArr;
}

frankenSplice([1, 2, 3], ['a','b','c','d'], 2);

You are actually getting this:

[["a", "b"], 1, 2, 3, ["b", "c"]]

You can use also this syntax, you just need a little change. Can you figure out what to do to push elemenents and not a subarray? Google can be your friend in this case.
