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!
It is amazing. I saw another TH-camr 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!
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.
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
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!
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.
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!
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.
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.
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
The example on the preview is not a mistake. In case posts are changed, postId won’t help. And even more: if posts are changed with the same data, postId will hide that unnecessary update (that degrades a performance). A lost reference in case of selectedPost will help to discover that error early. So, a developer can either fix the redundant update, or to cleanup selectedPost before the update
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 😅
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 !!
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

@It's Aaron Glad to hear that🙌 keep it up
Hello Lama, make please a video about useMemo, useCallback, useReducer)))
you forgot a "please" in there

@@operupal thank you
@@operupal, The “please” should be before “make”.

Not using TypeScript is just asking for trouble and endless nights.

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.
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!
Yes please ! Explain all the hooks, everybody needs a refresh and you are very good at explaining.
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!

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
Thank you for all this lama :) I learnt alot from you in the past year 🥳
Please make video on useReducer ...you are the greatest teacher i came across in my learning till now
plz make video on UseMemo and useCallback
I faced same issue yesterday and got its solution today while casually watching this video.
Safak you are the best! Thank you! Please make a Full Stack app with TypeScript.

Can you do a video about useReducer, maybe expanding the example in this video? That will be great.
Thanks!

An absolute gem of an explainer video.Can't seem to find it in your github 2022 repo.
Handle form onSubmit event. It does not render on every input, handle once, if form value affect another form value, only create for them
Thanks lama, this video give me a new knowledge
What a refined explanation!!! .This guy knows the core issues that juniors unknowingly do.
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 th-cam.com/video/tIdNeoHniEY/w-d-xo.html this one
Your insight is pure gold Lama Dev! Thanks for sharing your knowledge & experience~
This video is so helpful. Please create this type of videos more.

Loved it brother, learning a lot ... Keep it up for us

Good video bro, good reminder for people going fast!
I'd love to see useMemo and useReducer sometime, thanks for everything, you really help us a lot.
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.
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
Very nice explaination . This one video solved my many problems.
Nice tutorial, nice explanation of concepts. And before I forget,YES I want more videos on react 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've just found your channel, a lot of nice tips here. Thanks!
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
Woowwww i just started learning react last week and you gave me a bunch of informations with this video, thank you so much 💗💗
In the 4 part of your video, you would add the changeUser handler once on the form tag.
Such an informative video! Many thanks for your tutorials. I've learnt from you a lot!
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 do love your content man, best Lama teacher ever!)
Your examples are the best way to explain 👍🏻
Well done Sir, an excellent example well executed. Thank you.

yo just saying. keep it up. learning new things from you always. 💓
Thank you for showing us the most common errors, you are very useful for us. ❤
I was really helpful.
Would love to watch more on useReducer hook
Thanks Lama. I’m starting to love react. Use to love Vue most but now switched to react 💯
Hazırlamış olduğunuz videolardan çok faydalanıyorum. Teşekkür ederim. Reducer konusunda yapacağınınız videoyu sabırla bekliyorum.
Use Callback video please
Great video lama dev can you please make a video on core differences between junior and senior dev
really great work.. keep it up.. expecting more videos like this... 🙏👏👏
Amazing stuff. Thank you Lama!!!
Thanks for the update, you are just as good as John Smilga❤️
Really amazing video
Great video 👍👏
Please go deeper into the useReducer usage next video
This is amazing, refresh memory, and remind what was forgotten. I would watch video about another hooks, and that hooks (noob, pro)
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 😅
Very awesomely explained!
Very good video, sir. Keep it up!
which color theme are you using in vs code?
Very useful. Tks a lot. I made some of these mistakes. Now, no more :D
Please do a reducer tutorial. This video was extremely helpful.
Last example is helpful. Use id instead of updating object or take action on whole object.
Hi, may i know what editor you are using?
I see the feature of multiple lines editing, that is amazing
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.
When using functional update, React will pass the latest state to your function.
Güzel açıklayıcı bir video olmuş hemşerim.Eline sağlık.
Amazing very informative. Thanks for sharing
can you make a react course with two dashboards, Frontend and Dashboard?
I would like to know about usereducer use cases. Thanks!
I just love the way you teach
You are great :)
Çok iyi iş çıkartmışsın abim.
We will more happy to see more such videos about react hooks and it's perfect use cases..❤️

Haha. Man this is so good
making me remember all the Junior mistakes I made like this years ago XD
Please provide a lecture on useMemo and useCallback
U are not a lama u are an G.O.A.T
Great work, learning lot
Great tips! Thank you
Can you make an usereducer example with the same code snippet ?
Please do more videos about all hooks, like the useReducer!
Nice content, what is the name of the font and vsc theme?
Nice tutorial. Thank you
Really nice videos.
Thanks 🤗
😮oh thanks you , Can useState work with attributes on mouse over and on mouse out?
And this is why I code in Vue. Vue's ref() state management eliminate these bugs and remove the confusion of using two functions per variable.
Make a functional and practical use reducer video please 🙏🏾
