Why does 'n + 1' not work here

Tell us what’s happening:
So I got the solution but was struggling for a long time as I had ‘n + 1’ in the last line of the for loop instead of ‘n++’. Why does ‘n + 1’ not work here?

  **Your code so far**


function frankenSplice(arr1, arr2, n) {
let a = arr2.slice(0, arr2.length);
let b = arr1.slice(0, arr1.length);
for (let i = 0; i < b.length; i++) {
  a.splice(n, 0, b[i]);
  n++;
}
  return a;
}

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

if you write n+1 you are not changing the value of n, to change the value of n you would need to write n=n+1
