Why ain't this solution working

Tell us what’s happening: Hey guys, I need some help with this challenge. First I know it says slice and splice and I’m not using any of that, this is my first try with the challenge so I wanted to do it like this. The problem is when I run the tests everything is fine except for the condition “All elements from the first array should be added to the second array in their original order.”. I printed the outputs and it does the right job so I can’t figure out what’s the problem. Appreciate any help

  **Your code so far**


function frankenSplice(arr1, arr2, n) {
let newArr = [];

for (let i = 0; i < arr2.length; i++) {
  if (i === n) {
    for (let j = 0; j < arr1.length; j++) {
      newArr.push(arr1[j]);
    }
  }
  newArr.push(arr2[i]);
}
console.log(newArr);
return newArr;
}

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

It is failing because one of the test is frankenSplice([ 1, 2, 3, 4 ], [], 0) and since the second argument has a length of zero the first loop never happens causing the returned array to be empty

Yes!! You’re right! Thank you very much, I wasn´t understanding the empty array when printing the results of the tests. Already fixed it and passed the tests. Thanks again my friend!
