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.

[@nitishgupta8393]

Prop drilling disadvantages is, that in deep nested component, we have to unnecessary pass data to each child.

[@healthymindwisethinking8783]

Can you suggest me from where you have prepared for Reactjs.

[@nitishgupta8393]

@@healthymindwisethinking8783 bro it is not a single source, I have given much time.some of the thing u can follow as. Take react live class course by Sudhakar sharma sir from Nareshit, paid course. But structured. Then some KZbin which helped are. Code stepbystep, traversy media, pedro tech, code evolution, for redux ilive4coding. There are much, u explore yourself too.

setstate is asynchronous in nature.....it waits for the current function to complete before updating

[@nitishgupta8393]

Reference answer was super.... My answer would be Reference is for directly manipulating the dom element

[@muhammedaflah9812]

To force component rerender, we can't use useEffect. It can be achieved by changing the key prop.

[@devanshkaushik3481]

It can also be done with states within the component... Changing states will re-render the ui

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

[@sumitwadhwa8823]

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.

[@karanpanwar96]

Agreed 💯, abhi Banda jod tod k bola h 😅

[@mdsharique9685]

Correct bro, one can anytime check that thing by putting console inside useEffect.

[@nitishgupta8393]

Css preprocessor are sass less which compile the fancy css to generic css. Bootstrap and mui are the library

[@devwaliba1132]

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

[@siddharthsingh913]

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.

[@nitishgupta8393]

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.
