This project is a JavaScript implementation of a double-ended queue (deque) data structure, designed as a drop-in replacement for JavaScript arrays when used as a FIFO (First-In-First-Out) queue. It is implemented as a doubly linked circular list with a titular head node, offering improved performance for large-scale operations compared to arrays, especially when handling millions of entries. This project is ideal for developers working with Node.js who need an efficient and scalable FIFO queue for high-performance applications.
