6 State Mistakes Every Junior React Developer Makes

[@lionelsamain2348]

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]

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?

[@shahemhaddad2717]

@It's Aaron Did u?

[@lionelsamain2348]

@@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.

[@lionelsamain2348]

@It's Aaron Congratz mate ! What do you do ?

[@shahemhaddad2717]

@It's Aaron Glad to hear that🙌 keep it up

[@Corntrop]

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.

[@FidelGuajardo]

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.

[@alecssalecs8370]

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

[@writegoodcode]

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.

[@ferdinandeke9590]

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

[@John-mj1kk]

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

[@feriduncanselen9047]

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!

[@mariusj8542]

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.

[@Etubom]

An absolute gem of an explainer video.Can't seem to find it in your github 2022 repo.

[@xcrxwadda8287]

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

[@tanmayjain5821]

I faced same issue yesterday and got its solution today while casually watching this video.

[@figgsboson]

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!

[@MathaGaram]

What a refined explanation!!! .This guy knows the core issues that juniors unknowingly do.

[@dr.science9609]

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

[@damanpreetsingh8549]

I love this you should make more videos like this

[@morphine496]

I'd love to see useMemo and useReducer sometime, thanks for everything, you really help us a lot.

[@anshulsaxena3513]

yes definitely, please make a lecture on usereducer hook..... Thank you for this great tutorial sir, its kind one of the best and amazing

[@jeffwang8660]

It is amazing. I saw another KZbinr 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!

[@jotasenator]

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

[@Arabian_Abomination]

Thanks Lama. I’m starting to love react. Use to love Vue most but now switched to react 💯

[@mayanksinghal5913]

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

[@iamstickfigure]

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.

[@georgescuradu2275]

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.

[@norbertpascu6168]

Good video bro, good reminder for people going fast!

[@blackstonejimmy]

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!

[@marcosMartinez-wm7bd]

great content! Please share other hooks too

[@jvidalnunes]

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.

[@chrisplacktor1992]

Great video 👍👏 Please go deeper into the useReducer usage next video

[@welovephp]

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

[@mikhailvasilev5798]

In the 4 part of your video, you would add the changeUser handler once on the form tag.

[@raphaeljcm]

I've just found your channel, a lot of nice tips here. Thanks!

[@ferdinandeke9590]

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

Such an informative video! Many thanks for your tutorials. I've learnt from you a lot!

Handle form onSubmit event. It does not render on every input, handle once, if form value affect another form value, only create for them

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 !!

[@oscarandio2677]

This video is a gem

[@sc0or]

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

[@hassaanshah9819]

Nice tutorial. Thank you

[@alinesouza9297]

Great tutorial so precise, learn a lot if you can do some for useReducer it will be great. Much love from Côte d'ivoire 🇨🇮

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.

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 😅
