-By default, the `.sort()` method converts the elements of an array into strings, then sorts them alphabetically. This works well for strings, but not so well for numbers. For example, `10` comes before `2` when sorted as strings, but `2` comes before `10` when sorted as numbers.
+By default, the `.sort()` method converts the elements of an array into strings, then sorts them alphabetically. The `.sort()` method mutates the original array. This works well for strings, but not so well for numbers. For example, `10` comes before `2` when sorted as strings, but `2` comes before `10` when sorted as numbers.
 
 To fix this, you can pass in a callback function to the `.sort()` method. This function takes two arguments, which represent the two elements being compared. The function should return a value less than `0` if the first element should come before the second element, a value greater than `0` if the first element should come after the second element, and `0` if the two elements should remain in their current positions.

+
+The `.sort()` method mutates the original array - in other words, it modifies the order of the elements directly. This is generally considered bad practice, as it can result in unexpected side effects.
+
+Instead, you should use the `.toSorted()` method, which creates a new array. Change your `.sort()` call to `.toSorted()`. Do not modify the callback function.
+
+# --hints--
+
+You should use `.toSorted()` instead of `.sort()`.
+
+```js
+assert.notMatch(getMedian.toString(), /array\.sort/);
+assert.match(getMedian.toString(), /array\.toSorted/);
+```
+
+You should not modify the callback function.
+
+```js
+assert.match(code, /array\.toSorted\(\s*\(\s*a,\s*b\s*\)\s*=>\s*a\s*-\s*b\);?/);
