Hope you enjoyed the video! I also have a really cool and unique course that will teach you way more than this video. You'll learn how to build an actual complex project with React. It's called "Project React" and you can find it at cosden.solutions/project-react. Also, I have a free weekly newsletter called "Import React" with tutorials, news, and cool stuff about React! You can sign up at cosden.solutions/newsletter?s=ytc

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 }; }); };

@magiclover93466 ай бұрын
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

Darius, This is great, Thank you so much for these contents you put out, i just joined the discord and i am excited about what you have on there, it is really mind blowing... I want to suggest if you can make a YT short video, to talk about sample scenarios when it's is suitable to use useReducer instead of useState. I feel this might clarify things better for Jr react devs like me. Thank you.
@harag910 ай бұрын
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
@cosdensolutions10 ай бұрын
Yep exactly, that's actually what redux is! So you may want to consider it if your state is big enough

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

im currently rewriting this complex ui that was using useState to useReducer. I was using array index to track items and React kept getting confused and not updating the correct item. now 3 days laters it still doesnt work. Glad to see React become the new jQuery. Front end sucks

Hi! kind of new here with Reducer. If I'm not wrong, while calling the dispatch function, it basically calls the reducer function, and takes the the "action"(2nd params) as the actual parameter by ignoring the "state"(1st params) by default. Is that correct?
