Can speak English, can’t deliver in interviews
I feel like I can't speak fluently during interviews. I do know english well and use it daily to communicate, but the moment I'm in an interview, I just get stuck. since it's not my first language, I struggle to express what I actually feel. I know the answer in my head, but I just can’t deliver it properly at that moment. Please guide me

  • Q1. How React Works?
  • Ans. 

    React is a JavaScript library for building user interfaces that uses a virtual DOM to efficiently update the UI.

    • React creates a virtual DOM to represent the UI components.

    • When state or props change, React compares the virtual DOM with the actual DOM and updates only the necessary parts.

    • React uses a component-based architecture to build reusable UI elements.

    • React uses JSX, a syntax extension for JavaScript, to write com...

  • Q2. How Redux Works?
  • Ans. 

    Redux is a predictable state container for JavaScript apps.

    • Redux stores the entire state of the application in a single immutable object.

    • Actions are dispatched to describe state changes.

    • Reducers specify how the state changes in response to actions.

    • Components can subscribe to the Redux store to access the state.

    • Redux helps manage the state of complex applications and makes it easier to debug and test.

Round 1 - One-on-one 

(2 Questions)

  • Q1. Why is arrow function used
  • Ans. 

    Arrow functions are used for concise syntax, lexical scoping of 'this', and implicit return of single expressions.

    • Arrow functions have a more concise syntax compared to traditional function expressions.

    • Arrow functions do not bind their own 'this' value, instead they inherit 'this' from the containing scope.

    • Arrow functions automatically return the result of a single expression without needing the 'return' keyword.

  • Answered by AI
  • Q2. What is the need of de structuring syntax
  • Ans. 

    Destructuring syntax allows for easy extraction of values from arrays or objects in JavaScript.

    • Simplifies code by providing a concise way to extract multiple values from arrays or objects

    • Improves readability and maintainability of code

    • Can be used in function parameters to destructure objects directly

    • Example: const person = { name: 'John', age: 30 }; const { name, age } = person;

  • Q3. Javascript basic questions
  • Q4. React basic questions
  • Q5. Javascript eventloop related guess the output.
  • Ans. 

    Understanding the JavaScript event loop is crucial for predicting output in asynchronous code execution.

    • The event loop handles asynchronous operations in JavaScript, allowing non-blocking execution.

    • JavaScript uses a call stack and a message queue to manage execution contexts.

    • Example: setTimeout(() => console.log('A'), 0); console.log('B'); outputs 'B' then 'A'.

  • Q6. Write code in react of React.memo
  • Ans. 

    React.memo is a higher-order component that optimizes functional components by memoizing their output.

    • React.memo prevents unnecessary re-renders by memoizing the component's output based on props.

    • It is useful for functional components that render the same output given the same props.

    • Example usage: const MemoizedComponent = React.memo(MyComponent);

    • You can provide a custom comparison function as the second argument to Re...

  • Q2. What is the use of Context Api in React
  • Ans. 

    Context API is used in React to pass data through the component tree without having to pass props down manually at every level.

    • Avoids prop drilling by providing a way to share values like themes, user data, etc. across the component tree.

    • Helps in managing global state in React applications.
