Queue You JS

What is Queue JS?

This library has a Queue with the following methods: enqueue and dequeue. Enqueue adds item(s) to end of the Queue. Dequeue removes and returns the first item from the beginning of the queue.

Why?

Many algorithms use FIFO queues. Although javascript has build in methods for FIFO, the terms seem somewhat cryptic to me. Whenever I needed to add a queue, I found myself searching MDN for the correct array methods. As a result, I decided to write a very simple library / adapter to make working with queues a little easier. Now when I want to use a queue, I can simple install this package.

How to install

Import the package from npm

npm install queue-you-js

Import the package into your project.

Use the Queue

var Queue = require("queue-you-js")
var queue = new Queue();
queue.enqueue("hi");
queue.getItems();

OR

import Queue from 'queue-you-js';
const queue = new Queue();
queue.enqueue("hi");
queue.getItems();

To make a new, empty queue:

const queue = new Queue();

To create a new queue with multiple items:

const queue = new Queue(["item", "item", "more items"]);

Dequeue item:

queue.dequeu();

Peek first item--returns first item without removing it:

queue.peek();

Dequeue item and get it's value:

const firstItem = queue.dequeu();

Enqueue single item (Code below returns array: ["item"]):

queue.enqueue("item")

Enqueue multiple items:

queue.enqueue(["item1", "item2"])

Get items in the queue

queue.getItems()

Also:

queue.items
