function confirmEnding(str, target) {

var Newtarget = target.substring(-1);

var newString = str.substr(-1); // if i input str.substr(-1 -3); it will pass this test but fails the first one as expected

  if (Newtarget.length > 1 ) { //OMG is this cheating the FCC test??
    newString = str.substr(-1 -3);
  }


if (newString == Newtarget) {
    return true;
  }
  return false;
}
