Understanding Singly and Doubly Linked Lists with Real-Life Examples and JavaScript Code

Introduction Linked lists are one of the fundamental data structures used in computer science. They are dynamic, allowing efficient insertions and deletions. In this post, we’ll explore two types: Singly Linked Lists and Doubly Linked Lists, with real-life examples and JavaScript implementations. 1️⃣ Singly Linked List A Singly Linked List (SLL) consists of nodes where each node contains: A value (data) A next pointer pointing to the next node However, it does not have a reference to the previous node, so traversal is one-directional.
