Simple javascript queue implementation for several test projects.

javascript-queue.js

'use strict';

function Queue() {
  return {
    entries: [],
    enqueue(value) {
      this.entries.push(value);
    },
    dequeue() {
      return this.entries.shift();
    },
  };
}

const q = new Queue();

q.enqueue(8);
q.enqueue(6);
q.enqueue(7);

console.log(`+${q.dequeue()}`);
q.enqueue(5);

let current;

while (current = q.dequeue()) {
  console.log(`-${current}`);
}
