6 React Interview Questions You Have to Know

Pretty good explanation for beginners to understand the concepts

Awesome insights, thanks bud

jeez, seeing this reminds me of my time as a junior dev.
I wish i had chatgpt in that days

In the context of a react app, for mvc, wouldn't the model be the backend, the controller be your javascript, and the front end be the view? And since react components encapsulate jacascript along with jsx, can you really separate them into a view and controller?

Just a small suggestion, there is too much unnecessary information instead of direct question and answer. Would be great to cut to the chest.

Thanks Pedro!!

Thank you Man! Really appreciate your effort to help people like me.

thank you for this video, Pedro. would review the concepts you've mentioned.

Really good video, thanks dude!

You're growing up right before our eyes!

thank you so much for this video it helped me understand some topics better and will definitely help me in my interview

super!

When you are explaining state and how it differs in React compared to the example of using a plain object, what you're referring to is a declarative programming style as opposed to imperative(writing all the implementation logic yourself).

thanks for the vid that was helpful

Really helpful Bro.

Amazing Video bro

Pedro ur an angel

Hi Pedro, good content, thanks for this video! I would just suggest on the Hooks rules question, another plus It's always a good practice start then with "use" on the name.

I've done dozens of interviews recently that these questions were in nearly all of them.

Thanks nwanne

I was asked
1. Virtual Dom
2. React Security
3. OOP Principles and Design Patterns
4. Idempotency
5. High Level Components and Functions.

Is #4 Like how to pass data on components?

Thank you for this video. I am in the process of interviewing React/React Native devs. Do you do consulting work?

Few more common question:
What is the exact difference between class component and functional component?(they’re are not expecting syntactic differences as answer)
How do you choose functional over class component ?
What exactly happens with Lazy loading and how code splitting works?
How is closures implemented in React.

unfortunately I failed the interview and I had no answers for these.

Please make some videos on redux if not already started

That's really helpful😃

It's really helpful!

Underrated video, this should have more views! Thx Pedro!

MVC is more of an Architecture where Design Patterns deals with structure of Classes in OOP. Like singleton, factory, façade and strategy etc ,

Hey pedro! Excellent content 😌
Would love a video from you going over and explaining about common react design patterns!

Looking forward to it 👏

Nice video and good information! Thanks! Have you tried Jotai instead of Redux?

tidy ur clothes ?

👍

One more rule for hooks - no hook inside another hook.

I've been asked these interview questions (which I remembered and wrote down) so it might help someone:

1. What is state hoisting
2. What are falsy values in js
3. Synchronous vs Asynchronous code
4. What is a purpose of a Function as a child
5. Presentational component vs container component
6. Why do we need keys for React lists
7. How to recognize closures in js
8. Difference between using fetch() and axios
9. Purpose of fragments
10. How to create a custom hook

Thanks, really it will usefull for me.

Thank you

þrðmð§m ?

I'm actually so glad that my coding bootcamp taught me deeply about the MVC pattern, on this case using Rails. It's easier than it seems.

Thank you the the good tipps

Thank you brother for kind information
