Asynchronous JavaScript - callbacks, promises and async-await - JavaScript Bangla ( বাংলা ) Tutorial
HTML-код
- Опубликовано: 15 ноя 2024
- Those who work or want to work with javascript have to work with asynchronous javascript regularly. Sometimes we write asynchronous code without even knowing how it works. Or sometimes, we just avoid writing asynchronous code just because we don't understand the concept. But without knowing Asynchronous concepts, you can't enhance the performance of your JavaScript front-end or Node.js back-end.
This video will help a beginner to understand Asynchronous behavior of JavaScript from absolute scratch. It can also help an intermediate JavaScript developer to refresh their concept on this topic. It will also make you familiar with all the syntactic sugars (callbacks, promises and async-await) behind Asynchronous JavaScript.

বাংলা ভাষায় এই রকম মানের একটা কন্টেন্ট ! জাস্ট অবাক হলাম। মূলত ইংলিশ চ্যানেল গুলা ফলো করা হয় । বাট বংলা ভাষায় এই রকম একটা চ্যানেল দেখে অনেক ভালো লাগলো। আপনার জন্য শুভ কামনা।
অনেক ধন্যবাদ। আশা করি সাথে থাকবেন। অনুরোধ থাকবে ভাল লাগলে ভিডিও গুলো ছড়িয়ে দিন।
সেইম, আমিও ইংলিশ কনটেন্ট ফলো করি। বাংলা ভাষায় এরকম টিউটোরিয়াল আমাকে অবাক করে দিছে, ধন্যবাদ সুমিত ব্রো
ভিডিও টা দেখেছিলাম অনেক আগেই।আজকে আবার দেখলাম।ধন্যবাদ সুমিত ভাইয়া এত কষ্ট করে ভিডিও বানানোর জন্য।বাংলাতে এমন কোয়ালিটিপূর্ণ ভিডিও পাওয়া সত্যিই সৌভাগ্যের ব্যাপার।
11AM - 3PM line by line async-await way te bujar try korlam sob. Inshallah, most of the thing is clear now. Thank you, Sir " ❤ "
10:26 Set timeout+ 21:52 callback function + 30:49 Promise +52:00 async await
thanks
Async Await নিয়ে অনেক্ষন ঘাটাঘাটির পরও কিছুই বুঝতে না পেরে সর্বশেষ এই ভিডিওটা পেলাম। বাংলা ভাষায় এই ধরণের কন্টেন্ট তারপরও আবার সেটা ফ্রি ! ভাবা যায় না। অসাধারণ বলা ছাড়া আর কোনো ভাষা নেই।
RUclips e ei topic 10-12 ta video dekhe satisfied na hoye obosese ei video ta dekhe satisfied holam. Onk dowa apnar jonno vai..
Osadharon content ❤
ধন্যবাদ। আমি এর আগে মশ ভাইয়ের ভিডিও দেখে টপিকটা বোঝার চেষ্টা করেছিলাম। কিছু বিষয় তখন ধরতে পারিনি। আপনার ভিডিও দেখে আমার কাছে সবকিছু পানির মত সহজ হয়ে গেছে। মশ ভাই নিঃসন্দেহে একজন ভাল শিক্ষক। কিন্তু আপনি তার থেকেও বেশি ভাল শিক্ষক।
One of the best content creators, best programmer, best teacher.. 3 years dhore asynchronous niye khub problem e silam.. 3 bosorer er weakness ke convert kore strengthen baniye dilen ek ghontar video diye.. Take love vai❤️❤️
এতদিন না বুঝে এসব ইউজ করতাম। .then .catch এসব তো মাথার উপর দিয়ে যাইত! hats off man. God bless you
In almost every weekend I study some random things I'm curious about. Following this I started my day with some JS stuff and guess what? I had a whole day tour in this channel. These tutorials are far better than most of what we get in our search results. Amazing! Please keep blessing on us with such tutorials. 🥰
thanks a lot for your amazing reviews
অসাধারণ! ভাইয়া আপনি খুব ভালো মানের একজন শিক্ষক। আমি এই প্রথম একজন অসাধারণ শিক্ষককে দেখলাম। আপনার ভিডিও কোয়ালিটি প্রিমিয়ামের থেকেও বেশি কিছু।
ভালবাসা ভাই। পাশে থাকবেন।
স্যার জাভাস্ক্রিপ্ট এতদিন কনফিউশন এর মধ্যে শিখতে ছিলাম হঠাৎ করে ইউটিউবে স্যার আপনার চ্যানেল পেয়ে যাই আলহামদুলিল্লাহ স্যার প্রতি টা বিষয় খুব সহজে বুুঝতে পারছি স্যার স্বার্থ্য ছাড়া আমাদের সবাইকে শিখাছেন স্যার অনেক ভালবাসা স্যার
অনেক ধন্যবাদ। আশা করি সাথেই থাকবেন।
ভিডিও টা দেখেছিলাম অনেক আগেই।আজকে আবার দেখলাম
Javascript revision ditesi, apnar video dekhe concept ekebare panir moto clear hoy gese, apnar presentation awesome. MDN er documentation'er shathe shathe apnar tutorial onek kaje ashtese
এক কথায় অসাধারণ।
Callback hell বুঝার অনেক চেষ্টা করেও ব্যর্থ হয়েছিলাম।
আপনার এই ভিডিও দেখে পরিষ্কার হলো।
কোনো Premium কোর্সেও আপনার মতো এতো সুন্দরভাবে বুঝায় কি না সন্দেহ আছে।
অনেক শুভকামনা আপনার জন্য।
ধন্যবাদ। যদি ভাল লাগে তাহলে channel টি subscribe করার অনুরোধ থাকলো।
অবশ্যই দাদা।
দুই বছর হলো channel টি follow করে আসছি। প্রতিনিয়ত নতুন কিছু শিখছি

I think it was best concept clear video that I ever seen .thanks a lot sir.may allah bless you.

Hello, I am starting my journey in programming arena just for two months. You just made my go through so easier with sublime vibes. Take a bow & standing ovation ❤️. Respect for you, sir ❤️
1st viewer from Rangamati
thanks for created helpful tutorial... ai bisoy ta confused hoye asi akon clear
I have already known these. But I learned callbacks, promises and async-await more deeply. Thank you brother!
Thanks.Great content. I have been referred and watched the first 15 minutes of the video. I can say it's a great presentation
one thing you have done wrong, it's bit technical. Regarding the Main thread, the Main thread runs and tracks until the setTimeOut(other asynchronous action) ends.I have seen the image you end main() before getting setTimeout Output
Thanks for taking the step to introduce this complex topic through an easy and interactive presentation
Thanks for pointing that out. I am well aware of that. But this content was for absolute beginners. What you are trying to say is way beyond the concept :-) That's why for simplicity, I intentionally skipped that. But it's true what you said. Thanks.
খুব সুন্দরভাবে বুঝিয়েছেন। ❤️

The lion is back in the programming world.
Ha ha
Wow, This is as clear as mineral water...❤
At 26:17 instead of using nested callbacks, I think following code would be more cleaner:
const handleOrder = (customer) => {
processOrder(customer, completeOrder);
};
takeOrder("customer 1", handleOrder);
Excellent and professional tutorial. The only thing little annoying was the music.
