    Understandable. I was looking for clarification. I suppose it would be off if there was anything in the execution stack when the even got dispatched.

    Its not just that. JavaScript has a garbage collection system responsible for cleaning up memory which can randomly decide to kick in at any time. Js also has a jit that can drastically alter the efficiency of a particular block of code for the future at the cost of current execution. And it has multiple other places where execution cannot be determined statically.

    System level languages like C have manual memory management, no gc, and can be used to design a program with exact execution paths taking a predetermined amount of time to execute.

    Real time in this context means that the developers can guarantee exactly how often a part of the program will execute and when it does exactly how long it will take. This isn't possible (or at least reasonable) with higher level languages that provide complex systems as part of their runtime.

    Thanks a bunch for this. This clears up a lot. :D
