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 RUclips would allow, I would like this video 10 times!
Продолжай работать в том же духе с 0-ми познаниями в JS, это прекрасно
Weird because after 2 months I don't???
Really cool😊
@@vapeurdepisse Congratulations, you can pick up your trophy at the corner of who gives an F parkway and totally pointless flex avenue.

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 :)
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 !
Would you say that only juniors watch these types of videos?
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...
@@kynshra8960 ya that was a catch
@@ionitaa you interview people that are already on your team?
@@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...
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.
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
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
I have never heard a better explanation.
Very clear, simple, many examples.
Immediately subscribed to the channel
Thanks for the refresher. You do a great job explaining concepts.
You're really the best. A good teacher indeed. Your videos are clearly explained and hands on practice. Thanks a bunch for all you do. Bless you!!!
It was a perfect description of the React hooks I have ever seen. Thank you so much!
Köszönöm szépen, a megfelelő tudást kaptam, pont annyira kifejtve, amennyire szükséges és tisztázódott a fejemben sok misztikum.
This has answered many questions I had about this particular hook. Thanks so much for the great content!
Very useful, I was searching for these frequently, and you have grouped it together in one video, thanks a lot!
For the first time I understood useEffect clean up. As always lama dev simplified everything. Thank you so much
Omg. You are the best man. Cleanest explanation ever. We need every hook tutorial from you.
Man you're so good at explaining these concepts, thanks! You're videos are always great!
Sir , you are great !!!!!!!
Please continue this series 🙏❣️
Top-notch presentation, with a clear explanation of the pitfalls when working with useEffect
Another much needed video ❤️
Fetch API vs separate folder for API calls( as we used in our Netflix project)
Beautifully explained. This will be my go-to channel now.
Após 1 ano de estudo só agora entendi com o não ter problemas com useEffect. O clean-up ajudou de mais
Vlw @Lama Dev
Been working with react for a while now and you just demystified a lot
you are so amazing....I just never seen an explanation so clean and easy to follow...thank you and keep up the good work
Beautiful! Thank you! Especially thanks for showing me how to write the clean up function. As well as the api clean up.
Such a good explanation and example. I've never seen someone explain react hook that easily and it's use cases
It's an amazing tutorial and I can find answers lots of questions the interviewer asked me regarding useEffect during interview
Great Video 💯
This is my first time commenting on a RUclips video because this video really deserves it 😊
Definitely going to watch other react videos.
Oh wow. This is by far the best guide on useEffect. I have been working with react for well over a year now still gotcha when it comes to useEffect. This enhanced my understanding. Thank you.
Maybe another guide on other React hooks?
This is so informative, as a beginner I do respect what you done in this instruction!!🎉
You explained really well, thanks for this refresher!

Best explanation about react performing !
Amazing video i rarely comment on videos but it was an amazing video. thank you for this effort
I hope you can also explain the following topics also
1) Using a callback in the useeffect
2) The problem faced in forms when the state is one render behind the text entered in the input field.
your explanation on "subscribing to api" was very good, earlier i seen it in react docs and had no understanding what it meant, thanks
Such an amazing tutorial! thanks a lot!
I think this is the most effective explanation I've ever experienced!
Amazingly easy to comprehend! Good examples and explanation :)
Such a great guide! Thanks 8)
Friday's are for tutorials and Docs, combining these two helps you leverage on your coding skills. I fell in love with these useEffect best practices. Good video lad
I really love your tutorial mate , keep going and i wish you best of luck ❤️ from Algeria 🇩🇿
Very good explanation. useEffect is always intimidating! Keep doing the intermediate level help videos!
What do you mean by intermediate isn't useEffect one of the basic react hooks?
@@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
@@Isaac-eh6uu I wouldnt call useEffect a basic hook. Its the hardest hook for people to understand.
@@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
wanted to say. " I wouldn't"
This one of the best usseEffect explanations I've seen. Thank you Lama Dev 🙏🏻
