Where do I belong (not solution).js

function getIndexToIns(arr, num) {
  let result;
  if (arr.indexOf(num) == -1) {
    let N = Math.min(...arr.filter(e => e > num));
    console.log(N);
    N = arr.indexOf(N)
    console.log(N)      
    result = N;
    // console.log(arr.indexOf(r))
  }else {
   result = arr.indexOf(num)
  }
  return result;
}

console.log(getIndexToIns([40, 60], 50));
