How do different queue implementations in JavaScript compare?

What are the different ways to implement a queue in JavaScript?

In JavaScript, you can implement a queue using arrays, linked lists, or even using built-in data structures like the Queue class in some libraries.

What are the pros and cons of using an array for a queue?

Using an array for a queue is simple and easy to implement, but it can be inefficient for large queues due to the need to shift elements when dequeuing.

How does a linked list compare to an array for queue implementation?

A linked list allows for efficient enqueue and dequeue operations without shifting elements, making it more suitable for larger queues.

Are there any libraries that provide queue implementations?

Yes, libraries like async and bull provide robust queue implementations with additional features like concurrency and job management.
