Question about setTimeout that I need answer to

Question

If you setTimeout to a very small value (e.g. 1ms, possibly even zero, but haven't checked that) it will execute as soon as your main code is finished. It won't execute before your main code is finished, because JavaScript is not multi-threaded.
