I can't remember what first brought me to your channel, but I must say, you're a wonderful teacher. You break things down succinctly. You ask the questions that newbie programmers would ask, and you provide the answers. You never seem to be in a rush, and you don't make us seem stupid by mentioning a concept and never explaining what it means. Again, you're a wonderful teacher. Thank you for your time and videos.

[@ForeverChip03]

I second u

[@UmeshKhiste]

One of the best channel to clear basic concept and more about programming language. Keep going...

[@Solo_playz]

What an explanation .until now I only use node js but didn't know how it works but from now I can explain to others what is node js and how it works very easily 💪👍👍🙏🙏🙏 Thanks Telusko.

The best video for any beginner looking forward to learn JS. Touched some important concepts but made them look very simple through some great explanation.

[@vigneshv1517]

I’ve finally found out what I am looking for. Cleared all of my doubts about node js. Thank you soo much for this video Navin

[@samirkrishnach3691]

Thank you very much sir for providing such wonderful video.I am watching your nodejs series and I have doubt in my brain since day 1 when i started series. Today my brain gets some rest because of your video.

[@abhinavbindra1727]

this is the most important thing to understand about node js as it tells us why and where should node js is more powerful. thanks sir

[@akankshagarg2204]

What an amazing tutorial. So crisp and clear. Keep teaching sir! 😊

[@srinivaskanuparthi1226]

hey bro i wasted my time till now about the concept of Node.js architecture from different sources. now really i am very clear about how Node.js works.thanks for amazing content and great explanation. thank you so much....

[@shree4641]

Watch till the end!! ohh Wow, I had a question regarding those workers(aren't those threads) and you said JS is Single-threaded? But you answered my question at the end. Thank you. You are Awesome.🙏

[@DikshaChaudhary-oc2do]

What a brilliant teacher you are 😇😇😇

[@jayak3768]

Thank you sir thank you for clarifying that node js does use multi thread behind the scene. Call back is not possible without multi thread. U need another thread to get the response and execute call back method. CPUs do not magically start executing methods upon request from other processes or external systems. There has to be a thread monitoring the incoming requests. This is the case from all the way assembly language to modern programming languages.

[@satyajitmahunta7906]

ULTRA LEVEL EXPLANATION ......Realy Awesome

[@biplabmishra857]

100 times better than udemy basic . Thanks bro for explaining nicely

[@sidique5269]

Best teacher in programming world

[@aqwcom]

Clearest explanation I've found thusfar.

[@ShubhamDubey-ox5hx]

Hi @Navin, I think you are incorrect in saying that libuv, in turn uses kernel to implement multithreading!!! In fact, libuv has been developed to handle asynchronous operations for which there is weak kernel support (like file and dns operations) and for cpu-intensive operations in core node modules like zlib and crypto. You had very well explained the nodejs working except for the last part, so if you can correct it, perhaps your audience would be benefitted!!!

[@6066ChetanKhairnar]

This one video Cleared many doubts thanks sir u are a real gem

[@thecloudstories]

[@mdashiqurrahman2665]

You are a real teacher. tnx

[@rajeshroshan8261]

Thanks for this amazing explanation. Could you please resolve my one query. If we have libuv library to handle multiple request then why we use clustering in node js.

[@kannanellis]

Got very Good understanding of how it is working..Thank you Bro..Pls add more videos

[@manansheth3064]

Amazing! Some of the best detailed explanations I have seen.

[@iMakeYoutubeConfused]

Thanks for this explanation I tried to explain this to one of my intreviewers when I said that behind the scenes Nodejs uses muliple threads but he was not convinced XD I want to send hime this video so bad

[@krishnareddybhupathi441]

Thank you so much... Navin Reddy sir ..

[@prathamjoshi5945]

thanx again sir, u r simply great to explore the concepts. may i request u to make a complete vdo like u have made for python as a complete website with mysql.

It is so informative.Please make a series of videos on React JS

[@raniguntikadi7470]

Excellent teaching.....very interesting....

Sir, you didn't add your last two videos in your Nodejs playlist. I bookmark your playlists so, whenever you upload a video kindly update your playlists too. And as always, thank you for providing us such valuable content!

[@3D4Dhellomictestig123]

very very Amazing Explanation about Nodejs and also how Single and multi thread is work...:)

[@saurabhbagade1178]

This is very thorough with his concepts and examples.😉😉

[@lings628]

Thank you for the clear explanation. I am curious to know what happens when all the workers are busy and not able to take any more tasks from the main single thread? Will these tasks get queued up until a worker is available, but the main thread will continue to accept new requests and queue up the tasks to the workers?

[@AshutoshSinghQuick]

Thank you! I finally found the answer as how nodejs uses libuv to use multiple threads!

[@manirajs4658]

Thank you Sir, Now, I got clear idea of when should use NodeJs and when should not use NodeJs.👏✨👏

[@amitthatey2611]

Wonderful Teacher, Thank you sir.

[@thatisai12]

your the Master Sir in Java World!

[@Pahadiballer]

finally i got the concept.Thank you so much.

[@naveenchowdary3042]

Take a bow to this man .

[@mayurnerkar9682]

Best explanation for nodejs Thanks You So Much !!

[@RedFlame64]

Nice explanation

[@binidabright1181]

Exactly the kind of explanation i was expecting. Thanks sir!!

[@ayushgoyal7133]

Bro you teach in a very interactive way, to me at least. Keep up the good work. 👌

[@fahimuddin3822]

Its just best description about Node js

[@minindu6582]

Nice Explanation and need more explanation of the event loop and the event queue

[@ekamjotkaur8381]

It couldn't be explained any better than this

[@heavenworld145]

Great jo... 💪💪💪💪 Keep it. I like your teaching style and accent. Plz give knowledge basic to advanced. 💪💪💪💪💪💪💪💪💪💪

[@dhruvjoshi1115]

cleared the concept beautifully

[@coolramama9]

Thank you Naveen garu, I have small doubt.. You mentioned that Node js is not good for Cpu intense task... what if there million number of clients accessing the same server at a time? Will node js has a capacity to handle multiple millions of requests at a time?

[@liveinthecity11211]

Love your content, Navin. Keep it up!

[@faxxo9635]

Sir, with respect we don't create multiple threads even under the hood for nodejs. so, using worker threads to handle multiple things ultimately block the queue rather than callstack of javascript execution, instead, we use epoll (assuming Linux) to maintain file descriptor and and its attached events. so, epoll is providing non-blocking i/o, not worker threads😅.

[@someshbaheti4640]

the concept was OP brother!!.Appreciate your work

[@Dhanshri007]

Very nice explanation sir but there is confusion about on non blocking i/0

[@Ritu1989videos]

Wow simple amazing how easy way you explained !!

[@deepeshsoni9532]

lovelly explained clear all my dought thank u

[@Mahesh-gq7fm]

Great explanation. But I have a doubt, why don't we run the CPU intensive tasks using libuv with kernel threading facility. What's the disadvantage of using it? Thank u very much.

[@peterchen6462]

Thanks for your explaintation. That's very useful

[@manojbhamre6062]

Just wow...great explanation... Found very good channel

[@mallik1123]

[@suryateja6103]

Sir, please make a playlist "swift tutorial for beginners " . it will be really helpful to many people. Moreover it will be much helpful to me . Please sir..... 🙏🙏🙏. This is my humble request

[@Rohith_S_Siddeshwara]

sir in 3:29 you said that tomcat server will assign multiple threads for all the requests.. if that server is requesting the other normal server which does not have multiple threads then what is the use of tomcat server providing threads.. sir please explain this

[@tanaykulkarni822]

Wonderful and Useful And Helpful Really Helped me in becoming a good Programmer
