At 4:12:10 The solution to the problem is adding log checks may be keeping the track is an option and retrying async

Harkirat cohort is way way way better than anyother course. Because you learn a lot, infact you learn more than the syllabus given. If you wanna learn, it will be like an individual coach. Polls, interaction, TA, offline videos etc . Just tto make you things clear...i really appreciate....thanks brdr ❤

[nathannyawaya]

"Harkirat, browsers to talk to a server? browsers to talk to a server via http, we have done this so many times, you create a express server", 😅 you make this concepts so easy,

1:48:11 "Kiska naam leliya" was Funny.

[SarthakBahuguna-ql]

about that question asked in interview he's considering that what if backend fail in 2nd and 3rd option and its okay you can revert back, what you want as the user that new feature in the website you visiting added after few minutes or the existing feature takes 10 sec more to load , In 2-3 seconds the load on you website get reduced a lot, generally you don't clear the cache, what if youtube or big companies clear there cache, that's why it's not recommended

[vishusharma]

Hey, I think your course is great, but I have a suggestion. It would be beneficial to introduce a learning system that includes repetition of building projects and logic building sessions. This would enable people to develop a thinking mindset and the ability to break down problems into smaller, manageable chunks. Without this, purchasing countless courses may not be of much use.

[SAGNIKSENGUPTA]

can you post a preview of one of your beginner courses as well just so that the newcomers can also get an idea abt the cohort

[pratikbade]

Blessed to having you harkirat bhaiya💎

[agTT]

I never would have realized that the Harkirat cohort is more valuable than I imagined. I have to buy this, the price is really justified, I wasted 6lac in engineering just to get this shitty job. All I needed was a teacher like you.

at 02:36:38 who was he talking about any context

[kumarsubhambili]

Hi Harkirat! Just finished off this video. Great Insights. I have a Question at 1:45:15 you said that inside a websocket connection we can send the data packets through UDP. And for web socket connection we first do http connection. So how can we have UDP inside HTTP?

[susmitshaw]

Prices have returned to normal. Please extend the pricing that was offered in the previous video for at least a day or two...

[ahadabdul]

I wanted to get the course from the start but i couldn't buy for some reasons . I'm really waiting for web3 cohort so for that what are the prerequisites?? It would be easier to understand when cohort starts ❤.

[shyamn]

hi, I want to make simple score update apo where i will use websocket api to send message(json format) and this will update the score. kindly suggest any simple method or paltform.

[Varma-fl]

Please make a video on prerequisites for your web 3 cohort ✨🙏
