JS Basic Algo: Slice and Splice

Curriculum Help JavaScript
#1

I wonder why my code wouldn’t pass the challenge. I print the result of my splice() and seems to be giving the result I want. Input arrays were not changed, and I have the index n just right. Hint me please. Tia!

function frankenSplice(arr1, arr2, n) {
  // It's alive. It's alive!
  
  
  let newArr2 = arr2.slice()
  
  newArr2.splice(n, 0, arr1);
  console.log(newArr2)

  return newArr2;

}

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

Figured it out. Here’s my new code:

function frankenSplice(arr1, arr2, n) {
  // It's alive. It's alive!
  
  
  let newArr2 = arr2.slice();
  
  for (let i = 0; i < arr1.length; i++){
    newArr2.splice(n++, 0, arr1[i]);
  }

  return newArr2;

}

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

So the problem was that my first code adds an array (arr1) inside arr2. I was trying not to use a for loop, but had to anyways. :smiley:
