Dude, you are soooo underrated. 600 views? this video deserves a million views. can't even tell you how many different videos i watched about useReducer and finally you found a way to explain it perfectly. Finally got it 🙏🙏 thank you thank you thank you..

honestly, you're underrated. i learned more things from you than my college course.

I just want to say that these react hooks videos are by far the best and easiest to understand. They are fantastic for new devs and senior devs just getting into react. 😊

Thank you so much! Your channel will grow lots with your great, clear, and concise explanations!

Thank you so much Cosden! I've seen so many videos but it's just amazing how you are making this so simple.

This series on React hooks has been super informative. Really appreciate this content, these may be the best explanation videos I have ever watched, for any language.

There is no other way to explain it easier than you did in this video... just mindblown :) Thanks for the video Cosden! 👏

I feel like I just made it over a slump/ hurdle I’ve been stuck in for too long. But seriously… you’re videos have been SO helpful is getting over these hang ups. I appreciate what you’re doing here.

It's important to understand the strictness of immutability is enforced. If you don't return a new object in your reducer the component will not re-render. This is a bit different if you're coming from redux-toolkit. Redux toolkit will give you a brand new object in your reducers. Great video

Please keep up doing videos like that! Very concise and clear!

Such a great tutorial! Thank you and just subscribed :)

Very clearly explained. Thanks for making this . Subscribed.

Your content is really very useful. Easy and simple. It makes it easy for me 🥰🥰🥰 The way you explain is very similar to Jonas Schmedtmann😅🥰

thank you so much for the explanation!

Thank you for explaining things so clearly! I finally understand the useReducer now! I do have one question. Around 12:19 you mentioned that "[useReducer] can update multiple pieces of state at once. If we had done this with useState, you probably would have had a state value for count and then a state value for error" I'm a little confused about what you meant by this. Are you saying that you would need two separate states for count and error? Couldn't we have a state that holds an object with both count and error values and do the same thing in the useReducer example, like this: const [state, setState] = useState({ count: 0, error: null }); const increment = () => { setState((prevState) => { const newCount = prevState.count + 1; const hasError = newCount > 5; return { ...prevState, count: hasError ? prevState.count : newCount, error: hasError ? "Maximum reached" : null }; }); }; const decrement = () => { setState((prevState) => { const newCount = prevState.count - 1; const hasError = newCount < 0; return { ...prevState, count: hasError ? prevState.count : newCount, error: hasError ? “Minimum reached" : null }; }); };

Thank you!

Great video! You helped me a lot. Thank you

1:28 to 1:48, just summarization and I already got what it does. I did not use it really, but used redux, so it absolutely made sense. Thanks!

even my english is very bad but i can understand evry word you saying , and that's help me to get the information , thanks bro❤

Great explanation.

Great video. I've watched several vids trying to explain useReducer, and each time a little more sinks in, I just have to go and use it. It looks so simple when it's all on one page within one component. but when I have several pages and several components, and then need to throw it into a useContext or something for it to be accessible to them all

I think if you find yourself having to update 4+ instances of state that all depend on each other in some capacity, its time to use useReducer

The best explanation I've ever heard. I wish the best from Ukraine

I first of all like your video before watching - that tells you the confidence I have in you. I'll follow you on social media if you make your handles available and more...

I'm really greatefull to you for making video like these.......

Really great video

hi, great tutorial what is this browser you used in this tutorial

Just great !!!

Really Good

Nice explanation! Really enjoyed that :) May I ask if you can do videos on implementing Typescript + React in Clean Architecture/DDD? These topics and specific tech stack are very few in this space, and would be valuable to junior devs who join bigger teams...tq! Hope to join the discord soon!

All things Simply Explained exactly.

Please try to do series on storybook, react testing and typescript

The 12:18 explains it.❤

voy aprendiendo y tambien me voy enamorando jajajajajajajajajajajajajaja muchas gracias🌹 mi crush de react, amor al primer video 😍 jajajjajjaja

Awesome

I remember again why I use Vue 😄

Bro ,we need beginners react project

Video on RTK query?

I'm a visual learner, and him murmuring about the technicalities and jargon instead of showing it then explaining what he did makes this tutorial painful to follow yet its still sufficient, ty

thanks

useReducers looks like the complicated version of useState..what am i missing? lol

very nice! But as a teacher it is also good to speak a little slower...that would be my wish. I ´ve seen lots of tube videos, where guys think to be clever and don´t think about pupils learning and bombard with talking...

it would be better if you did not used typescript

i'll never understand this stupid hook 😢

The useReducer hook, so clearly and succintly explained. Thank you very much. PS One of the few Tutors to illustrate React with TypeScript code. You have to be commended for that. {2023-10-18}
