Doubly Linked Lists (DLL)

Explore the concept of doubly linked lists, understanding how nodes with previous and next pointers enable bi-directional traversal. Learn how maintaining a tail pointer enhances performance in operations like deletion, helping you implement efficient doubly linked lists in JavaScript.

Introduction #

By now, you may have noticed a constraint that arises when dealing with singly-linked lists. For any function which does not operate at the head, we must traverse the whole list.

Furthermore, since a linked list can only be traversed in one ...
