1. Overview
Deleting the tail of a linked list in JavaScript is easy. All you have to do is find the second last node, assign the node.next of that node to be null, and you will have successfully deleted the tail of your linked list. You can iterate through the list to find the element and delete it from the list. Additionally, if you are deleting the first node, make sure to return the list. Time complexity for this operation is O(n).
2. Benefits Delete Linked List Tail In JavaScript
The benefits of deleting the tail of a linked list in JavaScript are numerous. By using a linked list, you can easily remove and add nodes without reorganizing the entire data structure. This saves time, as operations on a linked list are O(1) time complexity faster than the array.
Furthermore, you don’t need to re-index all items when deleting something from an array, which is not the case with a linked list. You can watch this video for more information about linked list problems. So, if you need to delete or add nodes often, consider using a linked list for your JavaScript application.

4. Conclusion
In conclusion, removing the tail node from a linked list in JavaScript is possible by pointing the head node to the second-to-last node and updating the tail pointer accordingly.
This can be done in a constant number of operations using the LinkedList.tail property. Furthermore, if it is a single-node linked list that needs to be removed, it can be done by setting both head and tail pointers to null.
