React js - Top 30 Interview Questions and Answers for Beginners

[@roast5077]

Sir I don't know if you'll ever read my comment or not, but if you do, know that, you have successfully helped a student who was not getting a job, land a job at exactly the field he wanted to work in, that is react, and the credit goes to your video. Thank you so much for that.

[@interviewhappy]

It's my pleasure my friend. I am very grateful for your kind words @roast5077

[@shinosukenohara.123]

Bro, can u tell what kind of react project is good for resume? Plzz help me bro, i am in big trouble, wont waste much of your time

[@blank.haruka]

Congrats! May I ask which questions were asked to you? Currently preparing for a Technical interview tomorrow :(( Thanks a lot!

[@VKY-XLR8]

​@@blank.harukahey hi, how is your interview went and may I ask for what questions were asked? TIA

[@blank.haruka]

@@VKY-XLR8 Hi! I was just asked basic questions about 1. What are props and states. 2. When should you use states. 3. What's your opinion on Tailwind? 3. What's your learning style if you don't know something?

[@maxinantony8255]

I have seen couple of other tutorials for React interview prep before coming to this one. But none of them were informative and simple as your lecture. Thank you so much for putting effort for helping people like me. Thank you so much.

[@interviewhappy]

Super thanks.... . I wish you all the best for your career.

I'm at the beginning of learning react def not ready for interviews, but this video was still very informative and I feel like got a pretty good overall summary of everything I'll be needing to learn

[@interviewhappy]

Thanks Hasim and all the best for your career.

[@arjunaggarwal3702]

Hi Happy, I'm currently a student in the US with experience working as a full-time Frontend Software Engineer. While preparing for interviews, I realized I needed to brush up on React, even though I’m already proficient. Your course is fantastic! It covers key React concepts that developers often overlook. I highly recommend this course for anyone preparing for interviews or wanting to get more familiar with essential React terminology.

[@interviewhappy]

Thanks for the kind words! I'm happy to hear it's been useful for you.

[@shaharyalbeg9871]

I think anyone who wants to learn React should go through this video first. This video will make a strong base of React in his/her mind.

[@interviewhappy]

Thanks for appreciating my efforts @shaharyalbeg9871

[@BalajiM-lj2yq]

I saw your JavaScript and react interview questions, It was very helpful to take me to final rounds and now I got an offer. Thank you so much for making clear videos with examples😊.keep up the good work🎉.

[@ramachandra7044]

I am preparing for interviews and this video is of great use. Please make part 2 for react and js as soon as possible. Your happy subscriber after subscribing to interview happy❤

[@interviewhappy]

[@YouAreWrongAndIAmRightBro]

perfect content for my next interview . i hope i will pass the interview . thank s for your work it mean a lot to me

[@interviewhappy]

Best of luck!

[@tomasburian6550]

This is a boss video and important not only to get the job but understand React and its structure and workings to use it better. From my experience not that many employers actually test theory during interviews, but you might appear more professional if you demonstrate you know this.

[@interviewhappy]

I agree, things should be know conceptually. But theory is good for remembering the keywords which helps in creating impressions during interviews.

[@PrajwalDhungana-im1in]

Appreciate the video. Well explained. Again, thanks a lot!

[@MrGwkrajesh]

Hi Happy, here I m sharing my testimony, I got 4 offers by attending interview's after watching your videos. Now I have joined top 1 company in India. Thanks for your help.
