Checked for every challenge mentioned but cannot get past through them for what reasons? please help.

Your code so far

function mutation(arr) {
  var str = arr[1].toLowerCase().split('');
  var ar = [];
  for (var i = 0; i < str.length; i++) {
    ar.push((arr[0].toLowerCase().indexOf(str[i])));
  }
  var art = ar.indexOf(0);
  ar.splice(art, 1);
  var final = ar.reduce(function(a, b) {
    return a * b;
  }, 1);
  return final > 0;
}

mutation(["floor", "for"]);
