![:triangular_flag_on_post:](https://forum.freecodecamp.com/images/emoji/emoji_one/triangular_flag_on_post.png?v=3 ":triangular_flag_on_post:") Remember to use <a>**`Read-Search-Ask`**</a> if you get stuck. Try to pair program ![:busts_in_silhouette:](https://forum.freecodecamp.com/images/emoji/emoji_one/busts_in_silhouette.png?v=3 ":busts_in_silhouette:") and write your own code ![:pencil:](https://forum.freecodecamp.com/images/emoji/emoji_one/pencil.png?v=3 ":pencil:")
### ![:checkered_flag:](https://forum.freecodecamp.com/images/emoji/emoji_one/checkered_flag.png?v=3 ":checkered_flag:") Problem Explanation:
In the game of golf each hole has a **par** meaning the average number of **strokes** a golfer is expected to make in order to sink the ball in a hole to complete the play. Depending on how far above or below **par** your **strokes** are, there is a different nickname.
Your function will be passed **par** and **strokes** arguments. You've to return the correct string according to this table which lists the strokes in order of priority; top (highest) to bottom (lowest):
Strokes | Return
:--------- | :-------------
1 | "Hole-in-one!"
<= par - 2 | "Eagle"
par - 1 | "Birdie"
par | "Par"
par + 1 | "Bogey"
par + 2 | "Double Bogey"
&gt;= par + 3 | "Go Home!"
**par** and **strokes** will always be numeric and positive.
* Change the code below `// Only change code below this line` and above `// Only change code above this line`.
* Ensure that you're editing the inside of the `golfScore` function.
* You will have to make the function return exactly the same string as shown shown in the table, depending on the value of the parameters **par** and **strokes** that are passed to your function.

## Problem Explanation
Change the code below `// Only change code below this line` and above `// Only change code above this line`.
Ensure that you're editing the inside of the `golfScore` function.
You will have to make the function return exactly the same string as shown shown in the table, depending on the value of the parameters **par** and **strokes** that are passed to your function.
### Hint 1
`+number -number` can be used to increase or decrease a parameter in your condition.

## ![:speech_balloon:](https://forum.freecodecamp.com/images/emoji/emoji_one/speech_balloon.png?v=3 ":speech_balloon:") Hint: 2
### Hint 2
You use `if / else if` chains to return different values in different scenarios.

## ![:speech_balloon:](https://forum.freecodecamp.com/images/emoji/emoji_one/speech_balloon.png?v=3 ":speech_balloon:") Hint: 3
### Hint 3
Control the flow of your function based on the tables order of priority - top (highest) to bottom (lowest) to return matching string values.

// Only change code below this line
if (strokes == 1) {
return "Hole-in-one!";
} else if (strokes <= par - 2) {
return "Eagle";

return "Double Bogey";
} else {
return "Go Home!";
}
// Only change code above this line
}
// Change these values to test
golfScore(5, 4);
### Code Explanation:
#### Code Explanation
* Compare the parameters **par** and **strokes** to return appropriate string values.
* `if / else if` chain is used for flow control.
* String "Go Home!" is returned for every condition where **strokes** is greater than or equal to **par + 3**.

## Code explanation
#### Code Explanation
Since we already have an array defined in the variable `names` we can take advantage of it and use it for our return statements using indexes (eg: `names[0] is the first one`). That way, if you ever need to change a specific result you wouldn't need to look for it inside the function, it'd be at the beginning, in your array.
