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.
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
Lifecycle method answer always say first react has three phase mounting, updating and unmounting of component. Then describe all the methods and their need

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.
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.
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.
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?
Plz help me bro, I have completed 3 months internship as react dev. I'm good in react and redux. I have pass 2 tach round in statup. What package should I take ?
I dont understand by asking bookish questions how can interview can judge him if he have really worked on that tech or not Such a stupid interviewer Firstly Reactjs is not framework its library someone go and tell her😂
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.
Ur confident more than interviewer also communication !! 👍
Firstly @starting I thought u r interviwer nd mam as student.😅
Thank you so much

spread to be used right side and rest to be left side
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.
Very helpful. Thank you so much

Thank you for this video. It will help me
I am yet to grab me first job in react.
Hope you will get soon
For deliberately re render in class component we have a lifecycle method should component update
Rest parameters to grab undefined parameters so it always should be last parameter in function.
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
Css preprocessor are sass less which compile the fancy css to generic css.
Bootstrap and mui are the library
Really helpful... Please upload more videos...

Lifecycle method answer always say first react has three phase mounting, updating and unmounting of component.
Then describe all the methods and their need
u also know he doesnt have 3 years exp...
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
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.

Its a witch company, that's all they ask. It's a stupid selection process honestly
OK thank you
setstate is asynchronous in nature.....it waits for the current function to complete before updating
To open the hyperlink in new tab target attribute used, target _blank
Thank you sahil...

Static position by default any elements get and it position one below next

You really fucked up this interview, will be surprised if you get offer. Anyways, “setState” returns promise and it is a asynchronous.
Thanks for feedback
@@ReactjsExpertTalks did you get the offer?
Subscribe I think... Refer to the component which is consuming context or redux store state
