qlist

qlist is a high-performance double-ended queue (deque), stack, and circular buffer implementation for Node.js. v0.14.0 provides fast O(1) operations for push/pop/shift/unshift and efficient circular buffer operations. It is designed for Node.js environments (any engine), focuses on raw speed and minimal memory overhead, and is authored by Andras. Less feature-rich than alternatives like `double-ended-queue` but optimized for speed in Node.js.
