Printing to either the console or to html happens async, but is blocked by calling window.prompt.

So while all input and print statements are encountered in normal order, the print's exit immediately without yet having actually printed

This means the next input takes control, blocking actual printing and so on indefinitely

The effect is that everything's only printed after all inputs are done

To prevent that, what's needed is to only execute the next window.prompt after actual printing has been done

Since we've no way to find out when that is, a timeout is used.
