How to use slice and splice challenge

Hi guys,i am trying to use splice() to put in copied element in arr1 to arr2

  **Your code so far**

function frankenSplice(arr1, arr2, n) {
let joinArr = arr1.slice();
for (let i = 0; i < arr1.length; i++)
joinArr = arr2.splice()

n++
return joinArr;
}

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

Challenge: Slice and Splice

Link to the challenge:

You will need to give some arguments to the methods, maybe look up how the method works

function frankenSplice(arr1, arr2, n) {

let joinArr = arr2.slice();

for (let i = 0; i < arr1.length; i++) {

joinArr.splice(n, 0, arr1[i]);

}

n++;

return joinArr;

}

console.log(frankenSplice([1, 2, 3], [4, 5, 6], 1));
why is it returning this [ 4, 3, 2, 1, 5, 6 ] instead of this [4, 1, 2, 3, 5]

You are putting each number at index n, you would get the numbers reversed for that
