## Introduction

Linked List is a popular data structure used to store and manage a collection of elements. Traversing a Linked List refers to visiting each node of the list in a specific order. In this article, we will explore the Linked List traversal algorithm and provide a JavaScript code snippet to illustrate its implementation.

Traversal is the process of visiting each node in a Linked List from the beginning until the end. It allows us to access and operate on the data stored in each node. Traversal is typically performed using a loop or recursive function that iterates over the nodes, following the pointers or references between them.

## Algorithm Implementation in JavaScript

Let's dive into the JavaScript implementation of the Linked List traversal algorithm. Below is a code snippet that demonstrates how to traverse a Linked List:

class Node {

constructor(data) {

this.data = data;

this.next = null;

}

}

constructor() {

}

const newNode = new Node(data);

} else {

while (current.next !== null) {

current = current.next;

}

current.next = newNode;

}

}

traverseList() {

while (current !== null) {

console.log(current.data);

current = current.next;

}

}

}

// Example usage

## Explanation of the Code

Let's break down the code snippet step by step:

1. The `Node` class represents a node in the Linked List. Each node contains a `data` property to store the value and a `next` property to reference the next node in the list.

2. The `LinkedList` class represents the Linked List data structure. It has a `head` property that points to the first node in the list.

3. The `addNode` method adds a new node to the end of the Linked List. It checks if the list is empty (i.e., `head` is null) and assigns the new node as the `head`. Otherwise, it traverses the list until it reaches the last node and appends the new node to the `next` property of the last node.

4. The `traverseList` method iterates through the Linked List, starting from the `head` node. It prints the data of each node and moves to the next node by updating the `current` variable to its `next` node.

5. In the example usage section, a new instance of the `LinkedList` class is created. Nodes with values 1, 2, and 3 are added to the list using the `addNode` method. Finally, the `traverseList` method is called to traverse and print the values of the Linked List.

## Conclusion

Traversing a Linked List is a fundamental operation when working with this data structure. By understanding the traversal algorithm and its implementation in JavaScript, you can effectively iterate through a Linked List, access the data in each node, and perform operations as needed.
