Write a JavaScript program to check whether two given integers are similar or not, if a given divisor divides both integers and it does not divide either

function checking_numbers(x, y, divisor) {
  if(x % divisor === 0 && y % divisor === 0 || x % divisor !== 0 && y % divisor !==
    0) {
    return true;
  }
  return false;
}

console.log(checking_numbers(10, 25, 5))
console.log(checking_numbers(10, 20, 5))
console.log(checking_numbers(10, 20, 4))
