Could you elaborate on the problem you're having with callbacks and requestAnimationFrame?

I initially posted this, but now I'm not sure if this is what you meant:

Don't do this:

    requestAnimationFrame(function () { 
        //a new instance of this function is created every time
    })
do this:

    var efficientFunc = function () {
        //this is created only once and is reused
        requestAnimationFrame(efficientFunc);
    }
    requestAnimationFrame(efficientFunc);  
Basically avoid writing anonymous functions for callbacks that are going to be callback-ed more than once.

Another thing that might help with memory is make sure you don't keep references to things you want garbage-collected.

E.g. if object `A` has a reference to object `B`, `B`'s memory won't be freed even if you never use it again. MDN has a better explanation and example [1]

As for books I'd recommend Effective Javascript by David Herman.

Yeah I'm still stuck. Not really sure if it's a problem with requestAnimationFrame anymore, though.

If you're so inclined, I'd appreciate if you'd take a look at my stack overflow question.

At this point, I'm either fundamentally screwed up in my design or have some small innocuous looking thing which is eating all of my memory.
