    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.

    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.
