Tell us what’s happening:
Estoy estancado con este desafió, he intentado modificar el código pero no veo el fallo.

Alguien me puede dar una sugerencia?

Your code so far


var names = ["Hole-in-one!", "Eagle", "Birdie", "Par", "Bogey", "Double Bogey", "Go Home!"];
function golfScore(par, strokes) {
  // Only change code below this line
  if (strokes == par 1){
  return "Hole-in-one!";
  }
  else if (strokes <= par -2){
  return "Eagle";
  }
  else if (strokes = par -1){
   return "Birdie";
  }
  else if (strokes == par){
  return "Par";
  }
  else if (strokes = par +1){
  return "Bogey";
  }
  else if (strokes = par 3){
  return "Go Home!";
}
  
  return "Change Me";
  // Only change code above this line
}

// Change these values to test
golfScore(5, 4);
