Interview preparation tips for other job seekers - Started with interview the guy named Nimish and he has around 3 years of experience in Grappus. He started good he asked basics of Java, DSA and logical coding. Interview took 1 hr but the best part comes now. I answered 80% of the questions in the interview and the question I don't know I didn't answered. By this time I got to know that I am not selected.
He asked me 3 coding questions and I was able to answer 2 questions but the last one that he asked I was not able to come up with the solution but still thinking.
He gave me the hint, Great! I answered. Now he said optimize it. But the worst thing that happened at the end that he said you know even the 2 class student can answer this question. You are not able to answer this.
Okay I get it you are best employee of your company. But you are taking interview not making anyone demotivated or Humiliated. If you don't want to select then just say I am done with the interview and reject. If 2nd class of student can answer it then hire him.

    Custom hooks in React are reusable functions that allow you to extract component logic into separate functions for better code organization and reusability.

    • Custom hooks are created using the 'use' prefix and can be used to share logic between components.

    • Use cases for custom hooks include fetching data from an API, handling form state, managing local storage, and more.

    • Example of a custom hook for API call: const useFetc...

  • Q2. What is the difference between useMemo and useCallback in React?
  • Ans. 

    useMemo is used to memoize a value, while useCallback is used to memoize a function.

    • useMemo is used to memoize a value and recompute it only when its dependencies change.

    • useCallback is used to memoize a callback function and prevent unnecessary re-renders.

    • Example: useMemo can be used to memoize the result of a complex computation, while useCallback can be used to memoize an event handler function.

  • Q5. What are the various state management techniques available in React?
  • Ans. 

    Various state management techniques in React include Context API, Redux, and local state.

    • Context API: React's built-in solution for passing data through the component tree without having to pass props down manually at every level.

    • Redux: A popular state management library for React applications, allowing for a centralized store to manage application state.

    • Local state: Managing state within individual components using us

  • Answered by AI
  • Q6. What is the architecture of Redux, and what purposes do middlewares serve within it?
  • Ans. 

    Redux is a predictable state container for JavaScript apps. Middlewares are functions that intercept actions before they reach the reducer.

    • Redux follows a unidirectional data flow architecture.

    • Middlewares in Redux are functions that can intercept, modify, or dispatch actions.

    • Common use cases for middlewares include logging, asynchronous API calls, and handling side effects.

  • Q7. What is hoisting in JavaScript?
  • Ans. 

    Hoisting in JavaScript is the behavior where variable and function declarations are moved to the top of their containing scope during the compilation phase.

    • Variable declarations are hoisted to the top of their scope, but not their initializations.

    • Function declarations are fully hoisted, meaning they can be called before they are declared.

    • Hoisting can lead to unexpected behavior if not understood properly.

  • Answered by AI
  • Q8. What is event bubbling in JavaScript?
  • Ans. 

    Event bubbling is the propagation of events from the target element up through its ancestors in the DOM tree.

    • Events triggered on a child element will 'bubble up' and trigger on parent elements.

    • Event listeners can be attached to parent elements to handle events from multiple child elements.

    • Stopping event propagation can be done using event.stopPropagation() or event.stopImmediatePropagation().

  • Answered by AI

  • Q13. What will be the output of the following JavaScript code fragment: `const a; function test() { console.log(a); }; test();`?
  • Ans. 

    The code will throw an error because 'a' is declared but not initialized.
