This is easily the best programming video I've ever seen. You took a subtle and tricky concept (one which I suspect most software engineers don't actually understand), and explained it simply enough that a child could understand. Not to mention excellent production values. Super excited to have found this channel, and I can't wait to see what you make next!
Great job One suggestion: try a background video with less volume, no lyrics (human sound), and slower beats. That music is not just supposed to make the viewer excited or attracted, just makes it a lill colorful. Thanks
Dude amazing video and excellent job on explaining this topic because it was true hassle for me too understand. Just a couple of tips for in the future: 1: Choose a different music with lower BPM and lower it by 20% 2: A better microfoon or remove static noise in post production For the rest killer video!!!
This is the best video I watched regarding the I/O and CPU tasks. The code example cleared many things for me. Thanks a lot man. Please keep making videos on software engineering topics.
Thank you! Really glad I landed on this video, I don't remember the last time someone explained things as simply and effectively as this. Keep up the good work! Will regularly check your channel for any doubts.
It's a great explanation of complex concept. Divinding work time into CPU and IO time is a realy great concept for understanding this. Now I understand why Node.js is so popuar for web development. Thanks!
Just found this video, great work man. My 2 cents: I think the conversation about asynchronousity is incomplete without thinking about how threads and context switching are handled at the OS level. Without the concepts of yielding, interrupts and a priority queue for threads, I was confused for the longest on time on how the computer just magically knows when to switch from one task to another and when it knows that an IO task is complete. I feel like the next step after this video would be to tackle scheduling in OSes because I feel like a lot of programmers on the internet find it to be impenetrable when it's really not that hard!
I agree. I watched the video expecting a more advanced explanation. I'm currently amateurly designing the scheduler of a multi-tasking processor and wanted to learn of current solutions.
Your voice is perfect for these videos! You've come so far in the last decade, awesome stuff! Works like clockwork...wink wink nudge nudge. Anyway, I enjoyed this. I'm subscribing and hitting the bell!
This is the best explanation I've seen on non-blocking I/O. Thank you SOOOO much for this video! It clarified so many questions I had. @4:20 of your video, you listed three examples of I/O (inactive time): - reading from filesystem - making network requests - waiting for time to pass Would executing a long-running database query qualify as a I/O or CPU? The database would be doing all the heavy compute. Would NodeJS be able to move onto other active tasks while the database query is running? Or will a thread be tied to the database query?

No need for me to leave a comment, then. You've said it perfectly my friend 👍😁
10000%. Honestly great video - thank you
2:10
Great explanation , finally I understood what is non blocking I/O .
🙌
Thought you did a fantastic job explaining Non-blocking I/O. I was super bummed when I saw you only had two other videos. Makes some more vids!!!
I will :)
Where did you go? 😢
Great video. Cleared up a lot of confusion regarding how javascript works as a single threaded server. 👍🏼
Glad you liked it!
Seriously, this video should be the must for every beginner learning nodejs. Super important concept, but in super easy words and animations.
Loved the analogies and animations!
This is how the knowledge should be taught. Thanks for sharing
Great job

i think this is the best computer science video ive ever watched with regards to visually understanding due to the graphics
Just what I needed. Thanks mehn

This is absolutely the best explanation video about async I've ever seen. Amazing work!
Thank you very much no one explains this topic well, or they don't explain it at all!
This was super helpful, thank you!
I usually don't comment. but you really make things very simple to understand. Thank you!
Excellent Video! best explanation so far with visual representation.
This is the most crisp and clear explanation for non blocking I/O in layman terms, thanks a lot
Best explanation I have come accross, on this topic.
I just wanted to break the like button by clicking on it many times.
What a great explaination sir
Thanks so much
I HAVE NEVER SEEN A BETTER TUTORIAL THAN THIS ONE DUUUUUDDDEEEE, YOU ARE AMAZING!!!
Man that's HUGE, i finally understand this heavy topic as if it was a piece of cake, you're the GOAT ♥♥ Thanks for your effort ♥
This was super well presented and produced. Keep up the good work!!

wow, each of these is better than the last. Your hard work really shows!!!

Thank you. Almost 10y fiddling with web dev and never bothered to check this, sounds awesome to implement
Absolutely mind-blowing video, hats off to you sir

Fantastic video, Alex. Your channel is VERY underrated.
Great video I hope you keep them coming
You're great at explaining things. It's much clearer to me now. Thanks.
you make great content, don't stop until the top
What a wonderful lecture on blocking!!
Thank you so much for this video. Best explanation ever !
Thanks for making this video, it's easy to understand
Found this on Reddit. This was really helpful. Thanks 👍
Bravo!!! Excellent explanation!! 👏👏👏
One of the best videos for the concept!!!
Wow! Explanation is so good with the graph.
This is a treasure! Such a great and simple explanation! Thank you
Good work, hope you have more similar video.

Great one! Keep it up Alex.
By far the best explanation! Keep up the fine work
You just explain it so well !
This is exactly the video I need.
very decently explained. now i understand when to pick a (non-)blocking io framework

thank you soo much for this video brother . love from INDIA
Great explanation.
Great explanation. Simple and precise. Exactly what I needed. Thanks.
amazing explanation, I learned redis uses similar model as nodejs, would love your video on that!
Wow this video was amazing, thank you so much
Great video because it explains a hard thing simple
It was super helpful. Thanks much for clarifying.
That's huge, great job, u saved my life.
Best explanation, Thanks for the video
Very well presented. Waiting for more of such content 😊
Thanks, all of your video are easily digested! Maybe you can decrease the background music volume to 10% or 20%.
Thanks so much, this was super helpful!

Awesome Video Bro❤️❤️
too good, I am subscribing
Great explanation! Thank you.
My gosh, where have you been my whole life.
Awesome video. Clean and crisp explanation. Not sure why there is one dislike. Just ignore it. Maybe it's from a non software engineering viewer 🤣
great work!
