Props vs state State is use to maintain variable and data at component level. While props is used to pass the data, in some case state as well. And if we pass state and setstate both via props. In next component we can change the state and hence props too.

Lifecycle method answer always say first react has three phase mounting, updating and unmounting of component. Then describe all the methods and their need
functional components are NOT the same as class components even with the introduction of hooks. Hooks work differently then class components life-cycle methods. For example: this.state in componentDidMount will always refer to the latest state whereas useEffect hook's callback will have state belonging to a particular render.
I think changing a object without spread operator is possible, but this waybit has a side effect, that object are reference type data type so every where it will change
This Interviewer doesn't really have in-depth knowledge of React in-my-opinion, a Technical interview is not a quiz and shouldn't be treated as such. Some of the questions asked require rote answers and do not pertain what react developers use in their day-to-day activities. Tech interviews should center on a core understanding of React(Virtual DOM and unidirectional data flow), React Hooks and state management techniques(Redux, Context) to manage apps at scale, and optimization techniques to build highly performant apps.
As per my knowledge functional component has state , have you read functional construction in js they declared with capital letter you also do same thing with react functional component , it has state , in programming every function has state , unless you make function which work on another function
Before the introduction of hooks, functional components were known as stateless components. But from react 16.8 onwards, with the introduction of hooks, functional components can have their own state and are on par with the class components.
Callback functions I would say, function which perform another or next task after completing the main task of function. It is by default synchronos. Closure functions are basically functions which keep remember the data or variable from their lexical scope.
Hi Sahil. First, thank you for sharing this interview. Can you please tell us how much salary did you negotiate with this company? Because I am really bad with salary negotiations and after I have done bad negotiation, i regret.
Sahil, i have 5 yrs total in full stack and 3 yrs in react....i am not getting calls because of 2 months notice period or maybe other reason...my resume is not getting shortlisted...can you please help?

Props vs state
State is use to maintain variable and data at component level. While props is used to pass the data, in some case state as well.
And if we pass state and setstate both via props. In next component we can change the state and hence props too.
Thank you for this video. It will help me
I am yet to grab me first job in react.
Hope you will get soon
Prop drilling disadvantages is, that in deep nested component, we have to unnecessary pass data to each child.
Can you suggest me from where you have prepared for Reactjs.

Really helpful... Please upload more videos...
Thanks..i will upload soon
Reference answer was super....
My answer would be
Reference is for directly manipulating the dom element
codevolution for the gooo
Rest parameters to grab undefined parameters so it always should be last parameter in function.
Very helpful. Thank you so much

To force component rerender, we can't use useEffect. It can be achieved by changing the key prop.
It can also be done with states within the component... Changing states will re-render the ui
functional components are NOT the same as class components even with the introduction of hooks. Hooks work differently then class components life-cycle methods. For example: this.state in componentDidMount will always refer to the latest state whereas useEffect hook's callback will have state belonging to a particular render.
Agreed 💯, abhi Banda jod tod k bola h 😅
Correct bro, one can anytime check that thing by putting console inside useEffect.
Correction: setState is async.
I was thinking the same
thank for this add coding round videos also ...

Its a witch company, that's all they ask. It's a stupid selection process honestly
setstate is asynchronous in nature.....it waits for the current function to complete before updating
Css preprocessor are sass less which compile the fancy css to generic css.
Bootstrap and mui are the library

For deliberately re render in class component we have a lifecycle method should component update
Reducer manage the state and keep the logic to mututate the state
where did you learn all this, can yo recommend resources to learn react in detail?

Bro she is asking relative and static position property relative and absolute..
Callback functions I would say, function which perform another or next task after completing the main task of function. It is by default synchronos.
Closure functions are basically functions which keep remember the data or variable from their lexical scope.
Static position by default any elements get and it position one below next
