I was searching the web yesterday for this and didn’t really find a simple way of doing this and suddenly, I remembered something.
It’s extremely simple, someone could build on it with all sorts of features but for now, here is an example:

As you can see there are two counters, one is counting up and the other down simultaneously.
Here is the start_thread function:
function thread_start(callback) { setTimeout(callback, 1); return true; }
The trick is that setTimeout *does not* block the execution and starts another thread to run the callback function
I hope this helps someone

Thanks Hamid. Using the setTimeout pattern, I have created a “Threaded” non blocking object with start/stop methods…

This is not threading. Javascript is single threaded (unless you use a worker). All you are doing is a very small piece of work on a timer. You will block execution doing this, you just don’t notice it because it is not doing anything intensive.
BTW if you want to pass parameters then something like:
setTimeout(function(){callback(parameter)}, 1);
