Your code so far

function golfScore(par, strokes) {
  // Only change code below this line
  if (strokes == 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 +2) {
    return "Double Bogey";
  } else {
    return "Go Home!";
  // Only change code above this line
// Change these values to test
golfScore(5, 4);```

**Link to the challenge:**

The meanings of “par” and “strokes” in golf doesn’t really matter for completing this challenge. The description tells you everything that you need to know.

If you’re curious though, “strokes” is the number of times you hit the ball. “Par” is the number of strokes it’s expected to take to get the ball in the hole (the average?)

Hopefully that points you in the right direction!
