JavaScript queue

This is a queue implementation for JavaScript with a convenient API that avoids use of the expensive (O(n)) Array.shift() operation.

var Queue = require('o1queue');

Create a new queue.

var q = new Queue();

Queue up some stuff.

q.enqueue('hello');
q.enqueue('world');

How big is it?

console.log(q.length); // 2

What's at the front?

console.log(q.peek()) // 'hello'

Remove some stuff.

while (q.length > 0) {
    console.log(q.dequeue()) // 'hello', 'world'
}
