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

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.

Thank you my man, I landed in Canada from Chile 4 months ago and have my first interview tomorrow. This video was indeed helpful, cheers!!!!

I would rename this channel Pedro"LifeSaver"Tech !

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

this will really be helpful to a lot of react devs hoping to land their first full time job.

bro, since the first time a watch one your video i thought, wow this guy looks like a brazilian, so i followed you in instagram and i got it, you're a truly fucking brazilian, hahaha. Deixando o inglês das ruas de lado, parabéns pelo conteúdo, Pedrão, tô assistindo vários vídeos do seu canal e, além de aprofundar nas tecnologias, tô treinando o inglês também. Forte abraço, irmão!

Your videos have really helped me. Thank you!

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

The DOM question got me a month ago. I still don't feel like I can explain it, thanks for covering this.

thank you so much ^^ a hidden gem video that mostly coach/youtubers/tutorials dont take notes

Thank you so much! Every topic is a breeze with you.

You're growing up right before our eyes!

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?

Hey Pedro. How is your learning of GoLang going? WIll you be making videos/tutorials based projects aroung GoLang in the future?

I spent my whole summer last year using golang for backend. I got pretty good with it, I can start making videos but I feel like there is a lack of demand for it.

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

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

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

Awesome insights, thanks bud

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

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.

Really good video, thanks dude!

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

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).

Pretty good explanation for beginners to understand the concepts

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

Super helpful as always, Pedro!

Thanks, great one

Very informative video Dear Sir 😇

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

Nice one, thanks.

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

Nodejs + a DB like mysql or mongo shouldn't take long. To be able to code with it I would say a month is enough, but to be really good it takes time. GraphQL is way more advanced, would not recommend starting with it.
