100 doors solution - how to input into code checker?

I believe I’ve managed a solution, and using the console from chrome I get my array back of [1, 4, 9, 16, 25, 36, 49, 64, 81]. However, the code checker tells me it does not return the expected result. I just want to make sure that I’m not missing something about the way freecodecamp’s checker works. Is there something else I should be doing?

Your code so far


var numdoors = 100;

function getFinalOpenedDoors (numDoors) {
  //our count of open vs closed doors
  var openDoors = [];
  //our array of doors. It will count upward. An even number is closed, odd is opened.
  var doors = Array(numdoors).fill(0);

    //only finds and toggles relevant doors for each runthrough. Subtract one to account for runthrough starting at 1 and doors starting at index 0.
    for (var runthrough = 1; runthrough < doors.length; runthrough ++) {
    var counter = runthrough;
    while (counter <= doors.length) {
      doors[(1 * counter) - 1] ++;
      counter += runthrough;
    }
  }

//if the door is an odd number, it is open. Add its index plus 1 to our door counter (door one is at index 0, so 0+1)
  for(var i = 0; i < doors.length; i++) {
    if (doors[i] % 2 == 1) {
      openDoors
  .push(i+1);
    } 
  }
  return openDoors;
}

getFinalOpenedDoors(numdoors);

Link to the challenge:

One thing you missing with you result are door number 100. You just need to set the doors.length to doors.length + 1. The reason is that iterration starts at 0 and ends at 99 :-).
