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);

for (let i=0; i<mediator.length; i++){
    let newArr2=arr2.splice(n,0,mediator[i]);
}

let and other variable keywords are for declaring new variables only.

Alright, missed that, thank you. Code still not passing though :face_with_raised_eyebrow:

arr2 has to remain the same, so you can’t use splice on arr1 or arr2.

6

But when would splice enter the code then? It’s required

You can use splice, but not on arr1 and arr2, since those variables have to remain unchanged.

You can use splice on another variable.
