Covers three classic JavaScript string interview problems: reversing a string, checking for palindromes, and determining if removing one character can make a palindrome. Explains the two-pointer technique as a memory-efficient alternative to array-based approaches, with O(n) time and O(1) space complexity. Also touches on JavaScript string internals like immutability, primitive wrapper objects, and Function.prototype.call(). Includes complexity analysis and best practices for solving string problems in interviews.
