A very classy snake

I have the habit of start my coding musings by branching away from other people's proposals.

In this case I found myself looking at this video, where the author codes the snake game in 4'30''

The video is very good and the code is purposefully and relentlessly hacky. And the game indeed works after that time. While I was looking at it I was thinking, wow, I cannot beat him at his own game, but is it really so much different between that

window.Namespace = window.Namespace || {};

// Usage:
// Namespace.Rolenamee.init({ prop1: '.prop1', prop2: '.prop2' })
const Rolename = (function Rolename(expose) {
  // private class/constructor
  function Implementor({ foo, bar }) {
    this.foo = $(foo);         // store a value that will be needed asyncronously
    $(bar).on("event", () => { // set up an asyncronous reaction
      this.foo.method();       // use the stored value asyncronously through =>'s lexical `this`

Exercise:

Given this calls:

Taskman.queue(2.5) { print 'world!' }
Taskman.queue(1.0) { print 'hello ' }

When we do this one:

Taskman.work
