 In most browsers, including Chrome and Firefox the internal timer continues "ticking" while showing `alert/confirm/prompt`.

 That limitation comes from ancient times and many scripts rely on it, so it exists for historical reasons.
 
-For server-side JavaScript, that limitation does not exist, and there exist other ways to schedule an immediate asynchronous job, like [setImmediate](https://nodejs.org/api/timers.html) for Node.js. So this note is browser-specific.

 - To cancel the execution, we should call `clearTimeout/clearInterval` with the value returned by `setTimeout/setInterval`.
 - Nested `setTimeout` calls are a more flexible alternative to `setInterval`, allowing us to set the time *between* executions more precisely.
 - Zero delay scheduling with `setTimeout(func, 0)` (the same as `setTimeout(func)`) is used to schedule the call "as soon as possible, but after the current script is complete".
-- The browser limits the minimal delay for five or more nested call of `setTimeout` or for `setInterval` (after 5th call) to 4ms. That's for historical reasons.

 Please note that all scheduling methods do not *guarantee* the exact delay.
