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
Just curious what level positions were these questions asked? Is this entry level, intermediate or senior level? Thanks.
@@davidtesno3384 these were for entry level, as a junior react dev
Thanks. Did you get the job?
😂 I can provide answers to only 3 of these questions.
@@MrNikola14 I'm a junior developer looking for entry level job.... And .... damn I can't answer these !
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.
Well, mastering design patterns is my next goal to achive, thanks man. Wish you good luck in the youtube journey
Best of luck!
Your videos have really helped me. Thank you!
I was asked
1. Virtual Dom
2. React Security
3. OOP Principles and Design Patterns
4. Idempotency
5. High Level Components and Functions.
Idempotency? Isn’t that too personal to ask?
@@MarushDenchev lmao
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 so much! Every topic is a breeze with you.
Thank you Man! Really appreciate your effort to help people like me.
this will really be helpful to a lot of react devs hoping to land their first full time job.
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!!!!
Best of luck!
How did it go?
@@zakhariihusar6975 super bad, they didn't ask me any of these lmao
@@XlON___ better luck next time!
Que te preguntaron? Conseguiste algún trabajo en Canadá?
Underrated video, this should have more views! Thx Pedro!
Super helpful as always, Pedro!
I would rename this channel Pedro"LifeSaver"Tech !
thank you so much ^^ a hidden gem video that mostly coach/youtubers/tutorials dont take notes
thank you so much for this video it helped me understand some topics better and will definitely help me in my interview
Awesome insights, thanks bud
Really good video, thanks dude!
The DOM question got me a month ago. I still don't feel like I can explain it, thanks for covering this.
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).
Nice video and good information! Thanks! Have you tried Jotai instead of Redux?
thank you for this video, Pedro. would review the concepts you've mentioned.
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!
Kkkkkkkk td mundo toma um susto qnd ver q sou br. Pra ser honesto se do nada eu visse um tutorial em ingles de um br eu ia achar top kkkkkkk Valeu mano!
Loved the video! Crisp, to the point and super helpful. Great work!
That's good, thanks!
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?
Thank you for this video. I am in the process of interviewing React/React Native devs. Do you do consulting work?
It's really helpful!
Pretty good explanation for beginners to understand the concepts
Thank you brother for kind information
Gracias Pedro👍
Very comprehensive 🙌
Glad it was helpful!
Thanks, great one
Nice one, thanks.
Thanks Pedro!!
Thank you the the good tipps
Thanks for the video
Very informative video Dear Sir 😇
jeez, seeing this reminds me of my time as a junior dev.
I wish i had chatgpt in that days
thanks for the vid that was helpful
Thanks, really it will usefull for me.
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 👏
That's really helpful😃
Need more videos on this topic
You're growing up right before our eyes!
thanks pedro
Really helpful Bro.
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.
Clear and simple
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.
Amazing Video bro
Thank you so much cutie ❤️ please make more such videos and crash course videos on firebase
Thank you
Nice tutorial
Pls make more videos like this 😃
More coming!
Just a small suggestion, there is too much unnecessary information instead of direct question and answer. Would be great to cut to the chest.
I've done dozens of interviews recently that these questions were in nearly all of them.
Boa Pedrinho
super!
Is #4 Like how to pass data on components?
Pedro ur an angel
god bless pedro tech
Thanks nwanne
Please make some videos on redux if not already started
bro How long I take to become back-end developer (learn nodejs mongodb(mysql) graphql ) I am reactjs/nextjs developer
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.
@@PedroTechnologies ooooo bro 10Q respect and love from Ethiopia
great vid, move that pen tho XD
Lmaoo how did you even see that
I can answer almost all answers but still no job :(
One more rule for hooks - no hook inside another hook.
👍
