Leetcode Reverse String In Javascript NYKo0ETz3q8 - Complete Information & Details

Web Reference: The entire logic for reversing a string is based on using the opposite directional two-pointer approach! We can reverse a string recursively by thinking of it as swapping the outermost characters, then reversing the inner substring. If we have pointers at both ends (l and r), we first recurse to handle the inner portion, then swap the current pair on the way back up.

The substr () method returns the portion of a string starting at the specified position and continuing for a given number of characters.
