printQueue.addToQueue(() => console.log("Item #1"));
printQueue.addToQueue(() => console.log("Item #2"));
printQueue.addToQueue(() => console.log("Item #3"), true); // put this task at the beginning of the queue
printQueue.addToQueue(() => console.log("Item #4"));
printQueue.addToQueue(() => console.log("Item #5"));

//=> Item #3
// 1 sec delay
// Item #1
