About Singly Linked List

A linear data structure where elements are stored in nodes. Each node contains a data field and a reference (or 'pointer') to the next node in the sequence. Unlike arrays, linked lists do not have a fixed size and allow for efficient insertions and deletions.

class Node {
    constructor(data) {
        this.data = data;
        this.next = null;
    }
}
class LinkedList {
    constructor() {
        this.head = null;
    }
    // ... insert, delete, search methods ...
    insertAtEnd(data) {
      const newNode = new Node(data);
      if (!this.head) {
          this.head = newNode;
          return;
      }
      let current = this.head;
      while (current.next) {
          current = current.next;
      }
      current.next = newNode;
    }
}
