lowkey might be the best channel for every js developer

[hasithapriyasad]

I already know this concept, but your way of teaching is top notch. well-done man

[sabukuna]

a video about deep copy and shallow copy would be noice.

[Neth-gv]

When the world needed him the most, he returned!!!

[khedr]

You deserve more views, this is such an underrated channel!

[JeezySlots]

coming here after watching legendary "Wth is event loop?" video...I must say, that legendary video laid the foundation and you built the building on top. Top notch, thank you.

[abdallahazme]

Producing this level of quality is no easy task. It requires numerous other APIs and event queues to add tasks and manage the loop through the tasks after the call stacks and timing are right.
Thanks a lot man. And I suggest to change this playlist to 50 things you didnt know about javascript 😂😂😂😂

[georgii_v]

OMG! Who are you? wizard? How do you do that? Unbelievable! This is the best EVER explanation on the Russian / English internet! Please DO NOT stop! Thanks! Thanks a lot! Can't even imagine how much time you spent on that video!

[sgeuxkm]

This channel is a hidden gem! I've heard a bit about event loop before, but the animation (and gags) made it look so simple. I'm definitely checking out other videos about JS

[Salaralali]

one of the best (if not the best) Videos on Youtube for the JS community. Masterpiece! 👏

[gamingcurse]

You are the role model, I will never thank you enough for the effort you do my 100 hats off for you sir

[seephor]

Probably the best explanation of the topics on YouTube. Excellent job. This video is way underrated.

[BrackProgrammerNOLA]

MISSED YOU been developing via JS for about 17v months. I've come really far! You've been a big part of my developer education. APPRECIATE YOU!

[bmehder]

This is how a video is done people. Looking forward to FP stuff.

[VloggerFJC]

Thank you for this video. You are the first person who could explain this topic on a really easy to understand way.

Thank you for your videos. They really helped me to understand JS better.

[mdyousufgazi]

welcome back. as always explanation is top notch

[harshp]

Thank you SIr, this video is very helpful for me to crack my first ever interview ❤

[elyoaprogrammer]

Excellent video about this key JS mechanism used by all the modern frameworks to perform the DOM update. One more reason why it’s important to know about it
