(13 Questions)

  • Q1. What is denbouncer and throttle
  • Ans. 

    Debouncer and throttle are techniques used to limit the frequency of function calls.

    • Debouncing delays the execution of a function until a certain amount of time has passed without the function being called again.

    • Throttling limits the frequency of function calls to a certain rate, executing the function at fixed intervals.

    • Debouncing is useful for events that may be triggered multiple times in quick succession, such as r...

  • Q2. What is curry function
  • Ans. 

    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 easier to compose and chain

    • Example: const add = (a) => (b) => a + b; add(2)(3) returns 5

  • Answered by AI
  • Q3. Implement curry function
  • Ans. 

    Curry function is a higher-order function that allows partial application of arguments.

    • Currying transforms a function that takes multiple arguments into a series of functions that take one argument each.

    • It returns a new function until all the arguments are received and then executes the original function.

    • Example: const add = (a, b) => a + b; const curriedAdd = curry(add); curriedAdd(2)(3) returns 5.

  • Answered by AI
  • Q4. What is promise.all()
  • Ans. 

    promise.all() is a method that takes an array of promises and returns a new promise that resolves when all promises in the array have resolved.

    • It is used to handle multiple asynchronous operations simultaneously.

    • If any of the promises in the array rejects, the returned promise will be rejected with the reason of the first rejected promise.

    • The resolved values of the promises are returned as an array in the same order as

  • Answered by AI
  • Q5. What is memoization?
  • Ans. 

    Memoization is a technique of caching the results of a function to improve performance.

    • Memoization is used to avoid redundant calculations by storing the results of a function and returning the cached result when the same inputs occur again.

    • It is commonly used in recursive functions and functions with expensive computations.

    • Memoization can be implemented manually or by using libraries like Lodash or Memoizee.

    • Example: M...

  • Answered by AI
  • Q6. What is closure in javascript
  • Ans. 

    Closure is a function that has access to its parent scope even after the parent function has returned.

    • Closure allows for private variables and functions in JavaScript.

    • It is created when a function returns another function.

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

    • Example: function outer() { let x = 10; return function inner() { console.log(x); } }

    • The inner function can access and mo...

  • Answered by AI
  • Q7. What is the problem with colosures
  • Ans. 

    Closures can cause memory leaks if not handled properly.

    • Closures can hold references to variables outside of their scope, preventing them from being garbage collected.

    • If closures are used excessively or not released properly, they can cause memory leaks.

    • To avoid memory leaks, make sure to release closures when they are no longer needed.

  • Answered by AI
  • Q8. Some output questions on SetTimeout to check closure knowledge
  • Q9. React lifecycle events
  • Q10. Major difference between class based components and class based components
  • Ans. 

    There is no difference between class based components and class based components.

    • There seems to be a typo in the question.

    • Assuming the question is about functional components vs class components, the major difference is that class components use a class to define the component while functional components are defined as functions.

    • Class components have access to lifecycle methods while functional components do not.

  • Q11. Shallow copy vs deep copy
  • Ans. 

    Shallow copy only copies the reference to an object while deep copy creates a new object with a new memory address.

    • Shallow copy is faster and uses less memory than deep copy.

    • In shallow copy, changes made to the original object will reflect in the copied object as well.

    • Deep copy creates a completely new object with its own memory space.

    • In JavaScript, arrays and objects are assigned by reference, so a shallow copy will o...

  • Answered by AI
  • Q12. How to do deep copy ?
  • Ans. 

    Deep copy creates a new object with the same values as the original object.

    • Use Object.assign() method to create a deep copy of an object.

    • For nested objects, use recursion to copy all levels.

    • For arrays, use slice() method to create a new array with the same values.

    • Avoid using spread operator for deep copy as it only creates a shallow copy.
