Thank you for the video.But for the 3 first ones, we can use "useState" by storing state into an object like const [{isLoading, isError, isIdle, data}, setState]=useState(()=>({isLoading:false, isError:false, isIdle:true, data:null})) to avoid a lot of transitions.And for update, using setState({...}).Also with React 18, the batch update feature will prevent from the transitions problem, and for the 3 first cases we can use useReducer or useState.For the 2 last once, when we combine all this with the context API, i think you are right but, there are also ways to use useState in a very effecient way.This is really an matter of opinion, experience and practice.English isn't my first language, so understand the mistkes.

useReducer looks similar to the reducer in a redux application. So, useReducer is it used in a non-redux application ?

[manjunathjadhav]

when to use useReducer?
u said
useState -> number, boolean, string
useReducer-> array or object


but using useState (useEffect) v can fetch array/object too
then y to use useReducer?

[adilsheikh]

I still don't understand that why should I use any of these? Why can't I export my own object having state & behavior both & then import it to use in any component.

[belqisshida]

Which is faster and performant while both works for us?
1. useState

2. useReducer

Bro create playlists about "React Helmet" for SEO purpose then your channel get 1million subscriber beleive me...

[pankajjoshi]

Local state Vs Global State. How a state can be local, it is always Global right? If i am defining const [state, setState] = useState('') this state is always global. Am i correct or missing something?

[liewweijun]

can someone please brief the meaning of related state transitions and business logic? I will appreciate it.
