fast-fixed-queue v1.2.0

This is not a code created by me, I just extracted it directly from node core, as this class in particular is not exported, so I can use it on my own solutions. I did this because this queue implementation showed a really good performance over simpler ones.

How to Install

npm i fast-fixed-queue

How to use it

Instantiate it:

const queue = new FastFixedQueue<TheItemTypeYouWant>();

Enqueue items using push:

queue.push(newItem)

Dequeue items using shift:

const olderItem = queue.shift();

This implementation doesn't have a built in method to determine the queue size, but you can check if it's empty using isEmpty:

while (!queue.isEmpty()) {
    console.log(queue.shift());
}

Is it worth it to use it?

We compared the performance of this package against @iter-tools/queue and native array, and the conclusions are: @iter-tools/queue got the best performance over all tested scenarios. That's why I'm deprecating that package. It doesn't worth it.
