/**
 * Microtask Queue vs Task Queue
 * Prioritisation between Microtask Queue (also named Job Queue) and Task Queue
 *
 * There are two queues for executing asynchronous javascript. The Micro Task queue has priority over the Task Queue.
 * If you would keep on filling the micro task queue, you would block the code on the task queue. 
 * Asynchronous code which returns objects (like promises) are getting added to the Micro Task Queue. 
 * Asynchronous code which leave no trace (like setTimeout()) are getting added to the Task Queue.
