Ok, so this has been bugging me for a while. I’ve had the nagging thought of eventListeners vs container looping.

For example, you could create a bunch of objects and store them in an array; make a loop that traverses the array and tells each object to execute a method. In contrast I could tie an eventListener to the object in it’s constructor function that tells it to perform a task every frame. Does anyone here know which would be more efficient? And on this note does anyone know of a good way of testing different techniques for optimization? I haven’t been able to find any. Thank you!!! :pirate3:
