React tutorial in Hindi #12 State with class component

[@kirtisoni21]

Thanks a lot sir, I have learned many things.

[@fatemapatel9122]

No, we can't use useState in class-component because, useState is a Hook and Hooks are not implement in class-component.

[@jawadullah4685]

Right

[@khyzersaleem]

React Class Components have built in State Object. You might have noticed that we used state earlier in the component constructor section. The state object is where you store property values that belongs to the component. When the state object changes, the component re-render. ONLY call useState() hooks inside a functional component: Hooks are created for functional components and should only be used in functional components. They don't work in class components. If you need to use state in the class component, then use the state object.

[@nabilalakhani4182]

ur videos are ultimate keep up the good work thanks

[@mshahdevs]

No, you cannot use the useState hook in class components in React. The useState hook is a feature of React functional components introduced with hooks in React 16.8.

[@subhendu2134]

In React, state is not public, state is private to the component in which it is defined. This means that the state is not accessible or modifiable by other components directly.

[@harmankaur3359]

clearly explained!

[@shoaib4x533]

Maza aagya sir 🔥🔥

[@saurabhmore5164]

Can we only define the state without giving any value or data?

[@ZahiidKhan262]

Yes empty

[@prosinging7853]

this.setState is onestep behind. tried with await in SetState but that also not working. what might be wrong.When I am testing api with postman .Getting proper result but at the time of SetState it is one step behind when I console warn after assigning state

[@khyzersaleem]

Use Arrow Function In OnClick Then Use this.setState

[@Pragya_Empower_Studies]

Thank you.............

[@ricky_una_16]

Sir I have a small doubt regarding state, apne bola state public hai but google mai private show kr raha hai. So which one is correct, please clear it. Anyone also can verify me about this doubt.

[@mohitpipaliya2594]

In React, state can be either public or private. Public State: Public state refers to the state that is accessible and modifiable from outside the component. It's typically used when the state needs to be shared across multiple components or when you want to update the state from a parent component. Public state is managed using the props system, where a parent component passes down state as props to its child components. This makes the state public and accessible to those child components. Private State: Private state refers to the state that is local and specific to a component. It's not directly accessible or modifiable from outside the component. Private state is managed using the useState or other state management tools within the component. It's used when you want to keep the state isolated to a specific component and avoid unintended interactions with other components. let me know if you still don't understand, I'll give you code example for better understanding

[@fea25akshaygirase79]

op lecture sir

[@navjyotyadav4053]

Is state public or private? you said, its public then we should be able to use it outside of component. And also you said, state can not be used outside the component. These two statements conflicts each other. I think state in react is private, not public. what do you think? Please reply here.

[@kevalhirpara6747]

bhai google me state private dikha rahi he

[@DeepakGupta-hj2dv]

Redux ke video kab aayege?

[@himanshuchauhan6520]

if i am using 2 this.state in the constructor() like this constructor() { super(); this.state={data:"Himanshu"} this.state={number:1} } but i am not getting any output on the browser until i click the button return ( {this.state.data} {this.state.number} this.Inc()}>Surname ); Can you tell me why ?

[@ChandanSingh-ww5hr]

@himanshuchauhan6520 bro you don't need to create a separate state just put all the state data together like this super(); this.state={data:"Himanshusu", number:1} this will work

[@ashurajput357]

​@@ChandanSingh-ww5hr yes because mentioning this.state two times is wrong because now they are now different objects.

[@ZahiidKhan262]

Sir state private hoti h na usko as a argument use krte h hm log dusre components me

[@tejasdeore8340]

No state public hoti h previous video me bataya h

[@apkaChotaBhai]

[@sachindandge764]

Hello sir i have been watching your this series but it seems to me difficult as I am a beginner.plz make a videos of react which will have small code snippets as an examples to understand it better..

[@frontendwale]

Hi Sachin, you may try to look on this kzbin.info/door/jL4SPbBlJoOKT_YZz6zISQ

[@nileshgore4790]

[@WebDeveloper831]

Sir apne bola he ke state public hote hy lekin chatgpt to private btaa rhee he ap ye confirm kar den...

[@nikhilgaming4147]

No,we can't use hooks inside the class component

[@test-k5i]

Sir why we are not use function keyword in that case

[@roshanpandey4041]

how state is public ?

[@Ayush37262]

State is private

[@sanketdeogade4490]

How to update state immediately using class component? Because whenever I try to do setState, it doesn't update immediately. We can use useEffect in functional components But what about class components? How can we do it?

[@aashitkumarsinha3459]

use componentDidMount life cycle

[@sanketdeogade]

@@aashitkumarsinha3459 How to make it work for last update of setState?

[@aashitkumarsinha3459]

@@sanketdeogade it get automatically render at time of states get loaded first time, but it also get called by React...when the state gets changes...

[@abhisheksinghtomar159]

Why we can't use this.apple here?

[@shaheenkhan6313]

I think no we cannot use useState in class component because it gives error

[@codestepbystep]

Right

[@ayaankh245]

because it is hook. Hooks are for function components only.

[@syedateeq1602]

we can use it example. const [state, setState] = useState({ count: 0 }); console.log(state.count); and update it like this setState({ count: state.count + 1 });

[@riteshgoswami1596]

hook in only for function component

[@riderzzone6373]
