Different applications of linked lists

Linked lists are a versatile data structure that can be used for a variety of tasks. Some of the most common applications of linked lists include:

• Undo and redo: Linked lists can be used to implement undo and redo functionality in applications. This is because linked lists can easily be traversed backwards, which allows you to easily undo changes that you have made.
• Breadth-first search: Linked lists can be used to implement breadth-first search, which is a way to traverse a graph. Breadth-first search is often used in applications like file explorers and web browsers.
• Linked list queue: A linked list queue is a data structure that uses a linked list to implement a queue. Queues are a type of data structure that stores data in a first-in, first-out (FIFO) order. Linked list queues are often used in applications like operating systems and networking.
• Linked list stack: A linked list stack is a data structure that uses a linked list to implement a stack. Stacks are a type of data structure that stores data in a last-in, first-out (LIFO) order. Linked list stacks are often used in applications like compilers and debuggers.

Examples in JavaScript

Here are some examples of how linked lists can be used in JavaScript:

• You can use a linked list to implement undo and redo functionality in a text editor.
• You can use a linked list to implement a breadth-first search algorithm in a file explorer.
• You can use a linked list queue to implement a queue in a web browser.
• You can use a linked list stack to implement a stack in a compiler.
