A simple Javascript Queue based on an Array wrap and using setters/getters. More explanations here : https://insertafter.com/blog-fifo_lifo_javascript.html

Queue.js

class Queue {
  constructor(...elements) {
    // Initializing the queue with given arguments 
    this.elements = [...elements];
  }
  // Proxying the push/shift methods
  push(...args) {
    return this.elements.push(...args);
  }
  shift(...args) {
    return this.elements.shift(...args);
  }
  // Add some length utility methods
  get length() {
    return this.elements.length;
  }
  set length(length) {
    return this.elements.length = length;
  }
}

// Usage
const q = new Queue(0,1);

q.push(2);

console.log(q.length); // 3

while(q.length)
	console.log(q.shift()); // 0, 1, 2
