Update: I did a newer implementation here

In an attempt to trace the program flow of our Javascript client application we needed a stack trace of function calls. We needed to eliminate unneeded redraw and keep the code flow intact.
Over at deep some amazing AOP stuff in Javascript can be found. So what we did to print the stack trace? only an advice is added before all the interrested functions (Javascript has enough reflective abilities for us to be able to inject these advices along our object graph dynamically). And now we have a nice and accurate call stack! Ofcourse many cases of redraw are gone now. And we introduced another feature into our Javascript beast, AOP capabilities!
