Slice and Splice is kicking my butt

JavaScript
1

Tell us what’s happening:
I tested my code in the console I am just getting an empty array. I am not sure what I am doing wrong

Your code so far


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

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

Slice and Splice  *****my solution******

function frankenSplice(arr1, arr2, n) {

var array = []; var array1 = [];

for(var i = 0; i < arr2.length; i++){

array.push(arr2[i]);}

for(var k = 0; k < arr1.length; k++){

array1.push(arr1[k]);}

array1.reverse();

for(var j = 0; j < array1.length; j++){

array.splice(n,0,array1[j]);}

return array;

}
