[@sergeylukin8740]

I work professionally with React for more than 5 years and still regularly fall into these traps. Understanding these concepts is essential, and this video explains them perfectly. If KZbin would allow, I would like this video 10 times!

[@artmax1998]

Продолжай работать в том же духе с 0-ми познаниями в JS, это прекрасно

[@vapeurdepisse]

Weird because after 2 months I don't???

[@bokyunggg]

Really cool😊

I've realy never seen any one who explains React hooks so well and all it's possible uses as well as what mistakes to avoid, This kind of knowledge is really what we are missing as junior developers, And i realy appreciate the effort man Thanks !

[@kynshra8960]

Would you say that only juniors watch these types of videos?

[@ionitaa]

All the juniors in my team know by heart the count and setTimeout example because it's a common interview question. But when you ask them to demo global state they gg. One guy just left the interview...

[@GagandeepSingh1984]

@@kynshra8960 ya that was a catch

[@vapeurdepisse]

@@ionitaa you interview people that are already on your team?

[@ionitaa]

​@@vapeurdepisse What? At the tech interview, 2 of the codepens we give candidates for junior positions are: 1. The useState and setTimeout question. Most people get it right. 2. A quick demo on how to share state acros a component tree. Most people give up or just give bad solutions to this. You don't have to get all code pens right to get hired...

[@jashgopani32]

I wish I had found this tutorial earlier. You have explained all the details of one of the most important hooks in a really intuitive manner ! Great work :)

[@johnbaquerocelis8148]

Great explainable video, thank you! Only a sneak peek about Axios. Since v0.22.0 we can use the AbortController passing the signal as an option rather than CancelToken as it is deprecated in new versions.

[@chizidotdev]

Your method of explanations are second to none Lama Dev! Thank you so much… Suggestion for next tutorial… useReducer vs useState, I can’t seem to get enough explanations for them

[@mykalesalad]

This is by far the most helpful react video I've ever seen, cleared up a ton of questions I had about strict mode and effect hooks

[@marctofan824]

I have never heard a better explanation. Very clear, simple, many examples. Immediately subscribed to the channel

[@yoJuicy]

Very good explanation. useEffect is always intimidating! Keep doing the intermediate level help videos!

[@Isaac-eh6uu]

What do you mean by intermediate isn't useEffect one of the basic react hooks?

[@feritperliare2890]

@@Isaac-eh6uu yes but to use react in a way that won’t burn a user’s computer you must use convoluted tricks for the hope that you render only 300 times

[@CapeSkill]

@@Isaac-eh6uu I wouldnt call useEffect a basic hook. Its the hardest hook for people to understand.

[@naidasdiary5730]

@@Isaac-eh6uu I watched at least 5 tutorials about use effect , still cannot wrap my head around it. So, yes , I would call it basic

[@naidasdiary5730]

wanted to say. " I wouldn't"

[@amirjafari7996]

It was a perfect description of the React hooks I have ever seen. Thank you so much!

[@hesoncontroler]

Thanks for the refresher. You do a great job explaining concepts.

[@softmerit25]

Omg. You are the best man. Cleanest explanation ever. We need every hook tutorial from you.

[@nobir98]

Such a good explanation and example. I've never seen someone explain react hook that easily and it's use cases

[@philipmwangi5270]

Hey Lama Dev, Awesome video. Could you do one on useCallback and how they relate with useEffect or just how to minimize alot of rerenders on your application

[@shobhit4935]

you are so amazing....I just never seen an explanation so clean and easy to follow...thank you and keep up the good work

[@farzeenzehra4892]
