Fixing the Linked List Traversal Issue in JavaScript

Implementing a linked list is a common exercise for learning about data structures in JavaScript. However, sometimes issues can arise that prevent our code from functioning as intended. One such issue is that the traverse method may not print the last element of the linked list. In this guide, we will identify the problem and propose a solution to ensure our linked list traverses correctly.

Understanding the Problem

You've created a simple linked list with the following operations:

Insert at Head: Adding a new element to the start of the list.

Insert at Tail: Adding a new element to the end of the list.

Traversal: Printing all the elements in the list.

Here's the initial implementation of the traverse method:
