In this tutorial, we will go over how to implement a singly linked list in JavaScript from scratch. We will start by creating a Node class with a constructor function that takes in data and sets the next pointer to null. Then, we will define a LinkedList class with a constructor function that initializes the head to null. We will implement the insertAtBeginning method that inserts a new node at the beginning of the list and updates the head pointer. We will also define a printList method that traverses the list and prints the data of each node. Finally, we will create a new linked list object and insert nodes with data values using the insertAtBeginning method. We will print the contents of the list to verify that the insertion was successful. This tutorial is suitable for beginners who want to learn the basics of linked lists and how to implement them in JavaScript.
