I don't understand why you don't have a lot more subscribers. I have went through several videos and found them very useful .

[camcairns]

Sina, just a note of appreciation - your content and presentation are immaculate. You are one of the few educators who can employ humor so it contributes rather than detracts.

Sina whoever chooses your music, please give him a raise. I have watched your videos so much that I can tell what topic it is based on the intro or background music.

Currently 8 weeks into a web development bootcamp and i'm extremely lost....your videos are really helping me out man thank you!

[aleclloydprobert]

This series is very well done, and extremely clear and useful. Can't wait for the episode on closures.

[lloydchan]

these edits are so clean and entertaining, i wish more people saw you

[karimmaged]

Not sure if you'll see this, it's a year old video.
I'm currently learning web development and your videos are one of the greatest resources I found.
You deliver the info in a light yet effective way.
Hopefully you won't give up on this channel and would continue publishing those awsome videos.

Good fellas ❤ I just watched it awhile ago, what a coincidence!

[riteeshpai]

I wasnt knowing for months like what it is to use this keyword with arrow functions.I legit didnt understand it.But now seeing your explaination made it all clear to me.You are a gem.

[Trolleger]

Sir, your content has been a great help for me learning coding and reviewing coding (I go to coding class) You incorparate humor actually good, you have good visuals, mic quality and just everything is Immaculate. Thank you

[otabekkadirov]

This is a great explanation, thank you Sina. You are doing a great job, so please don't stop.

I really liked the old setup with the window ALOT better. Also your voice sounded better in the old setup. In the new one you clearly hear the resounding from the walls.

[brunog]

Yeah, I'm a Brazilian guy and i really liked this vídeo, thanks a lot!

[viorelmnk]

i like the way you explain in detail and with examples and the way the videos are made, very modern, clean and each topic of the videos gets a "separate" part of the video, making it easy for us viewers.

[Speedhaak]

Appreciate the bite sized approach to this content. Sometimes when you are researching something and you're staring down the barrel of a 45 minute video it can be defeating.

Cheers :)

I'm studying to be a full stack developer, based in South Africa. I've seen a lot of webdev tutorial videos online but I'm yet to see someone who does it better! 👌

This is the first video I watch from your channel and I have to say it is really good. The animations, explanation and everything. Thank you so much

[Ratchet]

Wow! This really takes away the mystique of higher order functions for me after years of programming in TS. How they work is obvious to me now, hence this video did its job. I just never really gripped how functions sent in as arguments run the code for each element in a collection, but now seeing you write these higher order functions, I see how they do the processing in a black box just like they would for any other primitive argument type. Thank you!
