Seek and Destroy - parsing to a "realArray"

Tell us what’s happening:

I tried my code line by line in the Chrome console and it works fine. I believe my issue is I am failing to pass the initial argument “arr” into a actual array (realArr) so that I can apply the filter method. Any tips? Thank you!

Your code so far

function destroyer(arr) {
  // Remove all the values

let realArr = [arr];
let remains = realArr[0];
for (let i = 1; i < realArr.length; i++){
      remains = remains.filter((x) => x != realArr[i]);
  return remains;
destroyer([1, 2, 3, 1, 2, 3], 2, 3);
