What are some real-world uses of Deque in JavaScript?

Deque, or double-ended queue, is useful in scenarios like task scheduling, undo functionality, and managing browser history.

Can you give an example of how to implement a Deque in a task scheduler?

Sure! You can use a Deque to manage tasks by adding new tasks to the front and processing them from the back.

What libraries can I use to implement Deque in JavaScript?

You can use libraries like 'collections.js' or 'deque' which provide built-in Deque implementations for JavaScript.

Are there any performance benefits to using Deque over an array?

Yes, Deques allow for O(1) time complexity for adding/removing elements from both ends, unlike arrays which can be O(n).
