timeouts throttled to ≥ 4ms in modern browsers, settimeout()/setinterval() calls are throttled to a minimum of once every 4 ms when successive calls are triggered due to callback nesting (where the nesting level is at least a certain depth), or after certain number of successive intervals.

Common causes of memory leaks in extensions - Extensions
if your add-on makes use of long-lived
timeouts or uses window.setinterval(), you need to take special care to ensure your code won't accidentally leak content windows.
... therefore, your add-on should clean up such intervals and
timeouts when the corresponding content document is unloaded, by adding an unload event listener or by similar means.

timeouts can ensure that your code runs in a timely manner, but it can also allow you to cause lag or animation stutters by mandating that the browser call you when there's not enough time left for you to run without disrupting performance.
Using microtasks in JavaScript with queueMicrotask() - Web APIs
generally, it's about capturing or checking results, or performing cleanup, after the main body of a javascript execution context exits, but before any event handlers,
timeouts and intervals, or other callbacks are processed.
... this lets every call to sendmessage() made during the same iteration of the event loop add their messages to the same fetch() operation, without potentially having other tasks such as
timeouts or the like delay the transmission.

timeouts you should include the --no-
timeouts flag to make sure your tests don't end up failing because of mocha's arbitrary timeout (which is 3 seconds).
Browser chrome tests
clean up functions are also guaranteed to be called if your test

timeouts you won't pollute next running tests and causing them to fail.
About NSPR
such timers are normally used to specify
timeouts on i/o, waiting on condition variables and other rudimentary thread scheduling.
Date and Time
for functions that deal with the measurement of elapsed time and with
timeouts, see interval timing.
Introduction to NSPR
philosophically,
timeouts should be treated as explicit notifications, and therefore require the testing of the monitored data upon resumption.
PRLock
functions that operate on locks do not have
timeouts and are not interruptible.

to access the service, use: var dnsservice = components.classes["@mozilla.org/network/dns-service;1"] .createinstance(components.interfaces.nsidnsservice); note: starting in gecko 7.0, the "happy eyeballs" strategy is used to reduce lengthy
timeouts when attempting backup connections during attempts to connect from clients that have broken ipv6 connectivity.

In depth: Microtasks and the JavaScript runtime environment - Web APIs
starting with the addition of
timeouts and intervals as part of the web api (settimeout() and setinterval()), the javascript environment provided by web browsers has gradually advanced to include powerful features that enable scheduling of tasks, multi-threaded application development, and so forth.
performance.measure() - Web APIs
const markernamea = "example-marker-a" const markernameb = "example-marker-b" // run some nested
timeouts, and create a performancemark for each.
Web Locks API - Web APIs
web applications can avoid this through several strategies, such as ensuring lock requests are not nested, or are always well ordered, or have
timeouts.
window.postMessage() - Web APIs
as with any asynchronously-dispatched script (
timeouts, user-generated events), it is not possible for the caller of postmessage to detect when an event handler listening for events sent by postmessage throws an exception.
Keep-Alive - HTTP
note that
timeouts longer than the tcp timeout may be ignored if no keep-alive tcp message is set at the transport level.
Transport Layer Security - Web security
to mitigate this problem, modern browsers have implemented handshake
timeouts: since version 58, firefox implements a tls handshake timeout with a default value of 30 seconds.
