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.
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?
@@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.
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
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.
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 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!
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
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.
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!
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!
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!
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
Nice. I didn't now about the function version of setStateVar. Also, you may have left this out to avoid confusing people, but I'd recommend a "useMemo" on line 12 of the last bit of code in the video. Running a "find" call on every render is maybe not great. Not terrible for an array of 3, but "useMemo" would be a good practice for things like that. Or you could also use a Map for an id lookup of the product.
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.
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
At 14:23, you are not creating a new product in handleChoose(). You find the product in the array and save the object in selectedProduct. In increment(), you create a new array with all the products (map), and you replace the product with a new object with updated quantity. But selectedProduct is still the old object.
hello guys :D lama, i'm also one of your student for a long time and thanks for all ^^ i wanted to say that it's a great idea to start use typescript but in my opinion it's better if firstly we'll learn real-world password forgot and reset functionality with react and node and it be even better if we use next.js much often ^^ i'm waiting for it 😅
hi, can you explain more deeper about how to handle complex input (section 5 : useState vs useReducer) and how to do another actions after category (select) changed if we used useReducer
The multiple states with separate onChange functions is a mistake I made when creating a recipe app. I'm so annoyed that I did that because I understand updating properties of objects and spread operators, but was just so hung up on how stupid it was to have all these states that I couldn't figure out this method.
It's best to use functional update if the new state is based on previous one. When using functional update, React will pass the latest state to your function.
Please make the video of really complex form like including all the input tags like checkbox, and others and Image upload in React application using MERN stack !!
One question I have A object contains 1 lack records and B object contain 10 records , I need to return only 10objects from A , i am doing now for loop but getting performance issue , do we have any other solution?
if you can do a tutorial abt formik and how to use it with complexe form like u just did tags and all that stuf or just native with simpl form and input and thank uu for ur consideration

@It's Aaron Congratz mate ! What do you do ?
@It's Aaron Glad to hear that🙌 keep it up
Yes please ! Explain all the hooks, everybody needs a refresh and you are very good at explaining.
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.
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.

Hello Lama, make please a video about useMemo, useCallback, useReducer)))
you forgot a "please" in there

What a refined explanation!!! .This guy knows the core issues that juniors unknowingly do.
You are my teacher ❤️ if I reach success definitely I will mention you in all my success note
And you will really present in my success note
I love this you should make more videos like this
An absolute gem of an explainer video.Can't seem to find it in your github 2022 repo.
Please make video on useReducer ...you are the greatest teacher i came across in my learning till now
Thank you for all this lama :) I learnt alot from you in the past year 🥳
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
I faced same issue yesterday and got its solution today while casually watching this video.
Your insight is pure gold Lama Dev! Thanks for sharing your knowledge & experience~
Best video to understand useState and use it in the right way♥
yes definitely, please make a lecture on usereducer hook..... Thank you for this great tutorial sir, its kind one of the best and amazing
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
Can you do a video about useReducer, maybe expanding the example in this video? That will be great.
Woowwww i just started learning react last week and you gave me a bunch of informations with this video, thank you so much 💗💗
Safak you are the best! Thank you! Please make a Full Stack app with TypeScript.

This video is so helpful. Please create this type of videos more.
I'd love to see useMemo and useReducer sometime, thanks for everything, you really help us a lot.
Nice tutorial, nice explanation of concepts. And before I forget,YES I want more videos on react hooks
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
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.
Handle form onSubmit event. It does not render on every input, handle once, if form value affect another form value, only create for them
Hazırlamış olduğunuz videolardan çok faydalanıyorum. Teşekkür ederim. Reducer konusunda yapacağınınız videoyu sabırla bekliyorum.
Loved it brother, learning a lot ... Keep it up for us
Good video bro, good reminder for people going fast!
yo just saying. keep it up. learning new things from you always. 💓
Thanks Lama. I’m starting to love react. Use to love Vue most but now switched to react 💯
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
Thank you for showing us the most common errors, you are very useful for us. ❤
Your examples are the best way to explain 👍🏻
At 14:23, you are not creating a new product in handleChoose(). You find the product in the array and save the object in selectedProduct.
In increment(), you create a new array with all the products (map), and you replace the product with a new object with updated quantity. But selectedProduct is still the old object.
Please create this type of video again this really helps
Reducer context react toolkits
And all the unable to understand hooks
Thank you sir
Thanks for the update, you are just as good as John Smilga❤️
I do love your content man, best Lama teacher ever!)
Very nice explaination . This one video solved my many problems.
U are not a lama u are an G.O.A.T
I've just found your channel, a lot of nice tips here. Thanks!
Such an informative video! Many thanks for your tutorials. I've learnt from you a lot!
Really amazing video
really great work.. keep it up.. expecting more videos like this... 🙏👏👏
This is amazing, refresh memory, and remind what was forgotten. I would watch video about another hooks, and that hooks (noob, pro)
In the 4 part of your video, you would add the changeUser handler once on the form tag.
Amazing stuff. Thank you Lama!!!
I just love the way you teach
which color theme are you using in vs code?
Well done Sir, an excellent example well executed. Thank you.
Haha. Man this is so good
making me remember all the Junior mistakes I made like this years ago XD
I was really helpful.
Would love to watch more on useReducer hook
Very useful. Tks a lot. I made some of these mistakes. Now, no more :D
Güzel açıklayıcı bir video olmuş hemşerim.Eline sağlık.
You are great :)

Very awesomely explained!
Hi, may i know what editor you are using?
I see the feature of multiple lines editing, that is amazing
Great video lama dev can you please make a video on core differences between junior and senior dev
I would like to know about usereducer use cases. Thanks!
Can you make an usereducer example with the same code snippet ?
Great video 👍👏
Please go deeper into the useReducer usage next video
The multiple states with separate onChange functions is a mistake I made when creating a recipe app. I'm so annoyed that I did that because I understand updating properties of objects and spread operators, but was just so hung up on how stupid it was to have all these states that I couldn't figure out this method.
We will more happy to see more such videos about react hooks and it's perfect use cases..❤️
Great work, learning lot
Very good video, sir. Keep it up!
1. How functional update work with currentNumber?? There is currentNumber declaration 🤔
2. What is prev in setUser((prev)) ??
It's best to use functional update if the new state is based on previous one.

Please do a reducer tutorial. This video was extremely helpful.
Great tips! Thank you
This video is a gem
Great explanation.
Hello, can i get this code repository (Github) ?
Thanks.
Please make the video of really complex form like including all the input tags like checkbox, and others and Image upload in React application using MERN stack !!
Amazing very informative. Thanks for sharing
😮oh thanks you , Can useState work with attributes on mouse over and on mouse out?
Thanks for sharing, Lama,
One question I have A object contains 1 lack records and B object contain 10 records , I need to return only 10objects from A , i am doing now for loop but getting performance issue , do we have any other solution?
plz make video on UseMemo and useCallback
if you can do a tutorial abt formik and how to use it with complexe form like u just did tags and all that stuf or just native with simpl form and input and thank uu for ur consideration
Thanks Lama for this insightful video. Can you please do a video of how to use useEffect hook properly?
Can someone please explain in the first example from where the value of (currentValue) is coming from? inside the increaseAsync() function.
