Round 1 - Technical 

(3 Questions)

  • Q1. What are keys and what are their uses?
  • Ans. 

    Keys are unique identifiers for elements in a list in React, used for efficient rendering and updating.

    • Keys help React identify which items have changed, are added, or are removed in a list.

    • Keys should be unique among siblings, but don't need to be globally unique.

    • Using index as a key is not recommended as it can cause issues with component state.

    • Keys are important for performance optimization in React.

    • Example:

        {items.

  • Answered by AI
  • Q2. What is code splitting?
  • Ans. 

    Code splitting is a technique used to split a large bundle of code into smaller chunks that can be loaded on demand.

    • Code splitting helps improve performance by reducing initial load times.

    • It allows for lazy loading of code, meaning only the necessary code is loaded when needed.

    • Commonly used in React applications using dynamic imports or React.lazy().

  • Answered by AI
  • Q3. Is it advisable to use indexes as keys? If not, why?
  • Ans. 

    No, it is not advisable to use indexes as keys in React components.

    • Using indexes as keys can lead to performance issues and incorrect behavior when reordering or deleting items in a list.

    • It is recommended to use unique IDs as keys to ensure proper component rendering and reconciliation.

    • Example:

        {items.map((item, index) =>
      • {item}
      • )}

Interview preparation tips for other job seekers - Make the interview interactive, I got this input from another Senior. Before i went into the interview room the volunteers were telling all those who goes into Room No 1 is screwed. I was praying i don't get room no 1. But fortunately for me I got room no 1 because when the interviewer gave me the puzzle and handed over pen and paper he went back to relax his posture and when i explained i will fill the 5L Jar first, he immediately came forward to listen to me, at that moment i knew i got the job because i felt the previous candidates never made their interview interactive and that's why he went back to relax his posture.
