Data Structures and Algorithms — Linked List

A linked list is a linear data structure where elements (nodes) are connected using pointers. It is useful for dynamic memory allocation and efficient insertion/deletion compared to arrays.

// Simple Linked List Node in JavaScript
class Node {
  constructor(value) {
    this.value = value;
    this.next = null;
  }
}
const first = new Node(10);
first.next = new Node(20);
console.log(first.next.value); // Output: 20
