Intuition

Using the built-in Array.prototype.reverse() method in JavaScript is a straightforward and clean way to reverse an array.

Approach

s.reverse(): This method reverses the array in place, meaning the original array s is modified directly without using additional space for another array.

Complexity

Time complexity: $O(n)$, where $n$ is the length of the array. The reverse method iterates through the array and swaps elements, resulting in linear time complexity.
Space complexity: $O(1)$, as the reverse method operates in place and does not use additional space proportional to the size of the input.
