daqueue Build Status

All of the implementations of queues I found attached everything to the prototype and didn't make good of private encapsulation, getters, non-enumerable methods, etc.

This queue does not use Array#shift internally, so it keeps O(1) rather than O(n).

So here it is, a clean implementation of a queue written in straight simple es5.

API

Create a queue

var createQueue = require('daqueue');
 
var queue = createQueue(); // => Creates an empty queue
 
var queue = createQueue('hat', 'tree', 'golf'); // => Creates a queue with initial values

queue.size

The size property works exactly the same as length on Array.

var queue = createQueue(1, 2, 3);
 
queue.size // => 3

queue.front

A property containing the first item in the queue.

var queue = createQueue('hat', 'tree', 'golf');
 
queue.first // => 'hat'

queue.enqueue()

Add a new item to the queue. Returns the queue for chaining.

var queue = createQueue();
 
queue.enqueue('hat');
queue.enqueue('tree').enqueue('house');
 
// queue is => ['hat', 'tree', 'house']

queue.dequeue()

Gets the next item in the queue.

var queue = createQueue('hat', 'tree', 'golf');
 
queue.dequeue() // => 'hat'
// queue is => ['tree', 'golf']

queue.toString()

Get the current queue as a string.

var queue = createQueue(1, 2, 3);
 
queue.toString() // => "1,2,3"

queue.toArray()

Copy the current queue into a regular array.

var queue = createQueue(1, 2, 3);
 
queue.toArray() // => [1, 2, 3]
