Hey, I just wanted to let you know that I graduated this year. I finally have my Bachelor degree in management developement. And this is (partially) thanks to you ! I followed your Netflix tutorial and it helped me tremendously for one of my last assignments.
So you can go to sleep tonight knowing you made someone else's life better.
I'm 33 and this bachelor degree is my second one. I decided to study it while working for a job I hated in order to get out of it. It already opened so many opportunities to me and completely changed my professional life and my career perspectives. Thanks a lot, I'll keep following your videos because I learn so much every time.
Woah am 23 and fretting about my whole life. I better find a job quickly....
hey did the netflix tutorial help learn react or are you alread good with all the basics of reactt? i am going to try to code along with him in that tutorial so i can learn some more do you think its a good idea?
@@itsaaron6423 Did u?
@@shahemhaddad2717 yea got a job this week
@@slipstream01 I was close to nowhere with React when I followed this. It's a lot to process though so maybe you should do a few tiny exercises to understand the very basics, then start with this. But whatever you do he explains everything he does so you'll be able to follow. But you might struggle to understand what you do. And if you don't understand, well you won't remember.
Great content!! Please keep releasing these kind of videos about best practices or dos and don'ts in React. It helps a lot! Thanks for good work!
Hello Lama, make please a video about useMemo, useCallback, useReducer)))
you forgot a "please" in there
@@youusef101 corrected)
@@operupal thank you
@@operupal, The “please” should be before “make”.
Wow. I've been developing apps for months and I realized I didn't know 4 of them lol. Thanks for making us better developers. Please share other hooks too.

Your insight is pure gold Lama Dev! Thanks for sharing your knowledge & experience~
Yes please ! Explain all the hooks, everybody needs a refresh and you are very good at explaining.
for the last one, you could wrap the find one in usememo and pass the dependency as id, to prevent calculating it again and again when you have a lot of states.
hey, thank you so much for all your vids, especially on React hooks. I like that you make it simple to understand while maintaining content and the rationale behind it. Plus your voice and the way you speak is comforting haha, it helps with the stress of complex topics like this. thank you!
Thank you for all this lama :) I learnt alot from you in the past year 🥳
Hey Lama, I am going to start working tomorrow at my first software developer job. Thanks to your portfolio videos and other various videos I feel really confident for tomorrow. Thank you for uploading videos like this you are a life saver!
And also, it would be lovely if we start using typescript in both our nodejs and react builds, that also will cut down a lot of these kind of errors. i don't know why no matter how much of tutorials i watch out there, i always still wait for you to implement such stacks before i really feel comfortable with them, cos your explanations sink so well in my brains at just a glance
Not using TypeScript is just asking for trouble and endless nights.
Great content as always. Ive been using your approach to handle forms ever since your last video about handling forms 👍
where is that vedio of forms can you please put the link here?
@@zakidzz ruclips.net/video/tIdNeoHniEY/видео.html this one
Such an informative video! Many thanks for your tutorials. I've learnt from you a lot!
What a refined explanation!!! .This guy knows the core issues that juniors unknowingly do.
this is gold, thanks for your time doing this video, and thinking about the proper examples, i will share this on my linkedin. Wish you the best. thank you once more
Please make more educational videos like this ... They are very helpful and everyone loves them
would suggest a tutorial how to use product management tool like Trello
I've just found your channel, a lot of nice tips here. Thanks!
Very nice explaination . This one video solved my many problems.
It is amazing. I saw another RUclipsr recommended to use useState individually for each state, but I feel your suggestion of using them as an object is much better. I am interested in useReducer. Could you talk about it as well. Thanks!
Thank you for showing us the most common errors, you are very useful for us. ❤
Woowwww i just started learning react last week and you gave me a bunch of informations with this video, thank you so much 💗💗
Spot on! I feel like a fool for not understanding that we could define the whole model/object in the initial useState,I have used the standard && every time I use map.
Loved it brother, learning a lot ... Keep it up for us
Nice tutorial, nice explanation of concepts. And before I forget,YES I want more videos on react hooks
Your examples are the best way to explain 👍🏻
I love the examples LamaDev uses. He really thinks beforehand about what code snippets are the best to explain concepts. He is a master teacher.
This video is so helpful. Please create this type of videos more.
An absolute gem of an explainer video.Can't seem to find it in your github 2022 repo.
I do love your content man, best Lama teacher ever!)

Thanks Lama. I’m starting to love react. Use to love Vue most but now switched to react 💯
I was really helpful.
Would love to watch more on useReducer hook
Best video to understand useState and use it in the right way♥
Hazırlamış olduğunuz videolardan çok faydalanıyorum. Teşekkür ederim. Reducer konusunda yapacağınınız videoyu sabırla bekliyorum.
You are great :)
Çok iyi iş çıkartmışsın abim.

Very useful thanks❤
This is amazing, refresh memory, and remind what was forgotten. I would watch video about another hooks, and that hooks (noob, pro)
Very useful. Tks a lot. I made some of these mistakes. Now, no more :D
Really amazing video
Dude thanks alot i literally ran into this problem on back4app , and this enabled me to assign multiple properties seamlessly and organized
can i mention you in my tutorial as a reference ? for a better method than mine i am doing a typescript tutorial and this helped me out alot
Thanks 🙏 very useful
Great video 👍👏
Please go deeper into the useReducer usage next video
Great video lama dev can you please make a video on core differences between junior and senior dev
Haha. Man this is so good
making me remember all the Junior mistakes I made like this years ago XD
Thanks Lama for this insightful video. Can you please do a video of how to use useEffect hook properly?
Please create this type of video again this really helps
Reducer context react toolkits
And all the unable to understand hooks
Thank you sir
great content! Please share other hooks too
I’d love to watch a useReducer and context API tutorial from u. I watched the Redux one, but I personally believe context API is easier to understand.
Your really awesome 😎 thank you so much ☺️👌🏼👌🏼👌🏼
Great tutorial. Would be great if you can do the same for the other hooks
Please do a reducer tutorial. This video was extremely helpful.
Thanks a lot, bro!!!!!
Deus abençoe você!!!
it worked for me so i leaved a like and sub
Very very Helpful 🙂 👍
Nice Work!!!
Please make this for the other hooks aswell, would be very useful
Thank you, very much.
Thank you very much!!!
I'd love a more in-depth look at the useState -> useReducer example you showed - this hook always confuses me (the docs say it should be obvious if I'm familiar with Redux... however I am not familiar with Redux). Same with useMemo and some of the more obscure hooks actually - but I might just be getting greedy asking for them... fantastic video either way!
Great insight
Hey lama, great video as always 🙏... Can you show the useReducer e.g. that you have advised with form e.g. in video please... Thank you
A Hidden Gem
Thank you so much
Can you do a video about useReducer, maybe expanding the example in this video? That will be great.
Great tutorial so precise, learn a lot if you can do some for useReducer it will be great. Much love from Côte d'ivoire 🇨🇮
Thanks! It's great lesson!
Yes, I'd like to see a useReducer :) I don't understand it...
Please do more videos about all hooks, like the useReducer!
You are a really great man.
Thanks for this
Thank you so much.
Thank you!
Please continue!
This is very helpful
Thank you 🙂
And
Can you make another video of Redux like this
Hey, thanks for the interesting material. It would be nice to listen from you about useCallback/useReducer/useMemo, what's your opinion on reduce, are you trying to avoid due to the complexity of the code?
