This kind of stuff can be a great LLM benchmark as Opus basically screwed it up and created a monstrosity as solution on first try.

Interesting! It did well for a first try. This was my prompt:

Lets play elevator saga! Here's the initial implementation:

    {
        init: function(elevators, floors) {
              var elevator = elevators[0]; // Let's use the first elevator
            // Whenever the elevator is idle (has no more queued destinations) ...
            elevator.on("idle", function() {
                // let's go to all the floors (or did we forget one?)
                elevator.goToFloor(0);
                elevator.goToFloor(1);
            });
        },
        update: function(dt, elevators, floors) {
            // We normally don't need to do anything here
        }
    }
