A simple package to provide a queue class

Install using NPM

npm install @jaypaulincodes/ssqueue

Import the package with the following import statement:

import Queue from "@jaypaulincodes/ssqueue";

Once imported you can create a new queue:

const MY_QUEUE = new Queue();

You can use the enqueue() method to add items to the queue:

MY_QUEUE.enqueue("foo");

Using the dequeue() method you can retreive the next item in the queue, removing it from the queue in the process:

const nextItem = MY_QUEUE.dequeue();

Complete example code:

import Queue from "@jaypaulincodes/ssqueue";

const MY_QUEUE = new Queue();

MY_QUEUE.enqueue("dog");
MY_QUEUE.enqueue("cat");
MY_QUEUE.enqueue("frog");

console.log("Starting to process queue of not frogs");

while (MY_QUEUE.hasNext) {
    if (MY_QUEUE.peek() === "frog") {
        break;
    }

    console.log(`Processing queue item: ${MY_QUEUE.dequeue()}`);
}

console.log("Finished processing queue");

Output:

Starting to process queue of not frogs
Processing queue item: dog
Processing queue item: cat
Finished processing queue
