Interview Questionnaire 

4 Questions

  • Q1. What is hoisting ?

    Hoisting is a JavaScript mechanism where variables and function declarations are moved to the top of their scope.

    • Variables declared with var are hoisted to the top of their scope

    • Function declarations are hoisted before variables

    • Function expressions are not hoisted

    • Hoisting can lead to unexpected behavior and bugs

  • Answered by AI
  • Q2. What is useEffect ?
  • Ans. 

    useEffect is a hook in React that allows you to perform side effects in functional components.

    • It replaces componentDidMount, componentDidUpdate, and componentWillUnmount.

    • It takes two arguments: a function that performs the side effect and an array of dependencies.

    • The function is called after every render, unless the dependencies haven't changed.

    • Common use cases include fetching data, setting up event listeners, and upd...

  • Q3. What is function currying
  • Ans. 

    Function currying is a technique of transforming a function that takes multiple arguments into a sequence of functions that each take a single argument.

    • Currying allows partial application of a function.

    • It helps in creating reusable functions.

    • Curried functions are composable and can be easily combined to create new functions.

    • Currying can be achieved using closures or by using libraries like Lodash or Ramda.

    • Example: cons

  • Answered by AI
  • Q4. What is closures in js
  • Ans. 

    Closures are functions that have access to variables in their outer scope, even after the outer function has returned.

    • Closures are created when a function is defined inside another function.

    • The inner function has access to the outer function's variables and parameters.

    • Closures can be used to create private variables and methods.

    • Closures can also be used to create functions with pre-set arguments.
