**Tell us what’s happening:**

Hey, how to make more efficient and solve? Thanks

**Your code so far**

```
function frankenSplice(arr1, arr2, n) {
let newArr2=[];
let mediator = arr1.slice(0, arr1.length);
for (let i=0; i<mediator.length; i++){
let newArr2=arr2.splice(n,0,mediator[i]);
}
return newArr2;
}
frankenSplice([1, 2, 3], [4, 5, 6], 1);
```
