+Returns the minimum/maximum value of an array, after applying the provided function to set comparing rule.
+
+Use `Array.reduce()` in combination with the `comparator` function to get the appropriate element in the array.
+You can omit the second parameter, `comparator`, to use the default one that returns the minimum element in the array.
 
 ```js
-const reduceWhich = (arr, comparator = (a, b) => a - b) => arr.reduce(function (a, b) {
-    return comparator(a, b) >= 0 ? b : a;
-});
+const reduceWhich = (arr, comparator = (a, b) => a - b) => arr.reduce((a, b) => comparator(a, b) >= 0 ? b : a);
 ```
 
 ```js
 reduceWhich([1, 3, 2]); // 1
-
 reduceWhich([1, 3, 2], (a, b) => b - a); // 3
-
-reduceWhich([{name: 'Tom', age: 12}, {name: 'Jack', age: 18}, {name: 'Lucy', age: 9}], (a, b) => a.age - b.age) // {name: "Lucy", age: 9}
