This code is OK. You just don't understand it.

It does.

Why do you think so? When I run the example above in Firefox or Chrome
it works fine. I click "Run" and the loop starts and when I click
"Stop", it will stop again.

It does. You just don't understand how JavaScript works in a Browser.

Just creating a loop which never exists as long as "run" is not false
does not work if this should be something useful in the browser.
That's the reason where there are functions like setTimeout() or
setInterval() to keep things running in JavaScript while still being
able to handle events caused by the user.
