Linked List In JavaScript

by

1. Overview

Linked list JavaScript is a linear data structure similar to an array. It is a dynamic data structure, meaning elements can be added and removed at ease. A linked list consists of nodes that contain two properties – a value and a pointer – with each pointer referring to the next node in the list. Linked lists are extremely useful for implementing other data structures like queues and stacks. In JavaScript, Linked Lists are implemented using the Node class, which contains two properties: a value and a next property. The LinkedList class then has the head property that represents the initial node. Using this setup makes it easy to add, remove or modify elements in your Linked List.

2. How Linked List Work In JavaScript

Linked Lists are a type of data structure used to store information in an organized manner. In JavaScript, linked lists consist of nodes that each hold two items: the data and a pointer to the next node. Every node is connected to the next node via a pointer, forming a linear collection of elements. To create a linked list in JavaScript, you’ll need to create a function for creating Node objects and then add new nodes to the list. Linked Lists provide an efficient way to store and access data as they can grow or shrink as needed.

3. Different Operations On Linked List Using JavaScript

You can perform different operations on a Linked List using JavaScript. Creating a Node is the first step in creating a Linked List.

The Node contains two properties: value and pointer, with the latter referring to the next item in the list.

After creating a Node, you can append an element to the end of the list with the append(element) method. You can also use the indexOf(element) method to find an element’s position in the list. Additionally, Doubly Linked Lists are also supported by JavaScript, where each node contains two pointers – one pointing to the previous node and one pointing to the next node. With these operations, you can easily manipulate any linked list in JavaScript.

4. Real Life Examples For Linked list

Real-life examples of linked lists are everywhere. From music players, to train compartments and even web browsers, you can find linked list data structures in action. In a music player, each song is like a node in the linked list and when you press the “next” button, you are accessing the next node in the list. When it comes to trains, each compartment acts like a node in the linked list and the engine compartment is the head. Web browsers also use linked list data structures to keep track of your previous and next URLs. Large number arithmetic is another application for linked lists – with class LargeInt using a dynamic doubly linked list. As you can see, linked lists are an incredibly useful tool for organizing data efficiently!

5. Conclusion

Linked lists are a linear data structure that store data in individual objects called nodes. They offer several advantages over arrays, such as requiring less memory and being able to dynamically allocate and de-allocate space in the list. Traversing a linked list is done by starting at the head node and going to the end of the list. Singly linked lists are useful for dynamic applications as they don’t need to be stored in order like indexes. Lastly, circular singly linked lists have no beginning or end, which allows for efficient traversal of the entire list. Overall, linked lists are an effective data structure for handling dynamic data elements.
