he he, I watched one video, then each one keeps referencing other videos I should watch first. The rabbit hole goes so deep ha ha – thanks for linking the relevant mentioned videos
Sir, you are a good instructor glad I found this video. Thank you!
Amazing pace, clear voice, solid knowledge , mature and patient teaching. Sir , you are an awesome teacher.
This is a very simplistic explanation. The execution of JavaScript is always synchronous from a call stack. What setTimeout does is delay the moment that a callback is pushed into the stack. And it will push into the stack after X milliseconds which means that it will actually be executed after all the stack is done executing. So it may not even be executed after X milliseconds. If this happens on a browser, other tasks may be executed before the callback like Dom rendering for example.
Thank you from 2021🙂
Sir, your explanation is very lucid. I can't thank you enough.
it's not really the callbacks that makes it asynchronous but its the web APIs like settimeout which makes it asynchronous. its not like you create your own callback and it's magically asynchronous because javascript is songle threaded. the web APIs which aren't coming with the javasript runtime engine but with the browser is what makes thr ehole thing asynchronous
Play at 1.25x speed. It sounds like you're purposely talking slower than necessary to lengthen the video duration
Your channel has been a blessing
Thank you, it really helped me revising the concept.
this is pure gold <3
Could have been an opportunity to introduce the Event Loop topic and Blocking Threads vs non-blocking threads.
This is just a plug. Which I have to say, the guy has 20+ yrs of JS experince and his 'courses' are as weak as yesterdays unfinished can of beer. better of elsewhere if you want to understand callbacks, async
Awesome!
Thank you! Nobody explains JavaScript better than you! Is there a "async await" video? I wonder if i missed that somewhere.
thx from brazil! excelent.
nice videos
Thank you 🙂
one of your videos is numbered 97 but i cant find the playlist for it.
The best Asynchronous example I ever heard. Thank you, sir

Thank you sir ….am glad you'll do promises next
Thank you sir
Do you cover promises in your course?
