Basic threading in JavaScript; JavaScript Worker Threads

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:
http://images.code-head.com/code/javascript/js-threads.html

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 :)
