## 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.

(Using Multiple Conditional (Ternary) Operators)
```js
function golfScore(par, strokes) {
return (strokes == 1) ? names[0] :
(strokes <= par - 2) ? names[1] :
(strokes == par - 1) ? names[2] :
(strokes == par) ? names[3] :
(strokes == par + 1) ? names[4] :
(strokes == par + 2) ? names[5] :
(strokes >= par + 3) ? names[6] :
"Change Me";
}
