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!
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.

@@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.
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!
Your insight is pure gold Lama Dev! Thanks for sharing your knowledge & experience~
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!
Yes please ! Explain all the hooks, everybody needs a refresh and you are very good at explaining.
Thank you for all this lama :) I learnt alot from you in the past year 🥳
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.
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.
Such an informative video! Many thanks for your tutorials. I've learnt from you a lot!
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.

What a refined explanation!!! .This guy knows the core issues that juniors unknowingly do.
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
Nice tutorial, nice explanation of concepts. And before I forget,YES I want more videos on react hooks
Woowwww i just started learning react last week and you gave me a bunch of informations with this video, thank you so much 💗💗
I've just found your channel, a lot of nice tips here. Thanks!
It is amazing. I saw another KZreadr 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!
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.
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
Thank you for showing us the most common errors, you are very useful for us. ❤
This video is so helpful. Please create this type of videos more.
Very nice explaination . This one video solved my many problems.
Thank you so much, i'm writting a code yesterday e thinking about how to write my code in a better way. There was a lot of States hahaha, so now today youtube show me your video and was what i need. You got a new subscribe.
I do love your content man, best Lama teacher ever!)
Good video bro, good reminder for people going fast!
great insights Lama, thanks. And yes please i would love to understand properly how the "useMemo" hooks and the likes of it used for performance optimization works, and how we could implement that to improve performance of our apps. thanks once more
An absolute gem of an explainer video.Can't seem to find it in your github 2022 repo.
I'd love to see useMemo and useReducer sometime, thanks for everything, you really help us a lot.
really great work.. keep it up.. expecting more videos like this... 🙏👏👏
Well done Sir, an excellent example well executed. Thank you.
Your examples are the best way to explain 👍🏻

You are great :) Çok iyi iş çıkartmışsın abim.
I just love the way you teach
Güzel açıklayıcı bir video olmuş hemşerim.Eline sağlık.
Thanks Lama for this insightful video. Can you please do a video of how to use useEffect hook properly?
Best video to understand useState and use it in the right way♥
This is amazing, refresh memory, and remind what was forgotten. I would watch video about another hooks, and that hooks (noob, pro)
Thanks for the update, you are just as good as John Smilga❤️
Very useful thanks❤
Great video lama dev can you please make a video on core differences between junior and senior dev
Really amazing video
great content! Please share other hooks too
Nice Work!!!
Great tutorial. Would be great if you can do the same for the other hooks
Please create this type of video again this really helps Reducer context react toolkits And all the unable to understand hooks Thank you sir
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.
Hazırlamış olduğunuz videolardan çok faydalanıyorum. Teşekkür ederim. Reducer konusunda yapacağınınız videoyu sabırla bekliyorum.
Thanks 🙏 very useful
it worked for me so i leaved a like and sub
Great tutorial so precise, learn a lot if you can do some for useReducer it will be great. Much love from Côte d'ivoire 🇨🇮
Very useful. Tks a lot. I made some of these mistakes. Now, no more :D
This is very helpful Thank you 🙂 And Can you make another video of Redux like this
Please make this for the other hooks aswell, would be very useful
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!
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
You are a really great man.
Haha. Man this is so good making me remember all the Junior mistakes I made like this years ago XD
Your really awesome 😎 thank you so much ☺️👌🏼👌🏼👌🏼
Safak you are the best! Thank you! Please make a Full Stack app with TypeScript.
Please do a reducer tutorial. This video was extremely helpful.
Very very Helpful 🙂 👍
Great insight
good job.. keep it up
I faced same issue yesterday and got its solution today while casually watching this video.
love your work basically learned how to program from you... can we have typescript with react and ionic 😁 hopefully one day ill buy you a coffee to say thank you
Please continue!
Can you do a video about useReducer, maybe expanding the example in this video? That will be great.
A banger already
Thanks! It's great lesson! Yes, I'd like to see a useReducer :) I don't understand it...
Thank you very much!!!
Please do more videos about all hooks, like the useReducer!
Thank you, very much.
