 ### Percentile
 
-Calculate how many numbers are below the value and how many are the same value and
+Use `Array.filter()` to calculate how many numbers are below the value and how many are the same value and
 apply the percentile formula.
 
 ```js
-const percentile = (arr, val) => {
-  let below = 0, same = 0;
-  
-  for (const number of arr) {
-    if (number < val) below++;
-    if (number === val) same++;
-  }
-  
-  return 100 * (below + (0.5 * same)) / arr.length;
-};
+const percentile = (arr, val) =>
+  100 * (arr.filter(v => v < val).length + 0.5 * arr.filter(v => v === val).length) / arr.length;
 // percentile([1,2,3,4,5,6,7,8,9,10], 6) -> 55
  ```
