This is not the case, if your callback then goes off and does something asynchronous.

  Yes sorry I was thinking in terms of code that uses callbacks, not the async keyword. What I mean is that distinct from threading, where the following code could be interrupted between the first and second line of the function, by something that updates global: var global function addTheseToGlobal(a, b) { im = a + global return im + b }
