Round 1 - Technical 

(5 Questions)

  • Q1. What is Hoisting?
  • Ans. 

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

    • Variable and function declarations are hoisted to the top of their scope.

    • Only declarations are hoisted, not initializations.

    • Function declarations take precedence over variable declarations.

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

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

    Closures are functions that have access to variables from their containing scope even after the parent function has finished executing.

    • Closures allow functions to maintain access to variables from their outer scope

    • They are created when a function is defined within another function

    • Closures are commonly used in event handlers and callbacks

  • Answered by AI
  • Q3. What is Promises?
  • Ans. 

    Promises are a way to handle asynchronous operations in JavaScript, providing a cleaner alternative to callbacks.

    • Promises represent the eventual completion (or failure) of an asynchronous operation.

    • They allow you to chain multiple asynchronous operations together.

    • Promises have states: pending, fulfilled, or rejected.

    • You can handle the result of a promise using .then() and .catch() methods.

    • Example: const myPromise = new

  • Answered by AI
  • Q4. What is Callback Hell?
  • Ans. 

    Callback Hell is a situation in asynchronous programming where multiple nested callbacks make the code hard to read and maintain.

    • Occurs when multiple asynchronous operations are nested within each other

    • Leads to deeply nested code which is hard to read and maintain

    • Can be avoided by using Promises or async/await syntax

  • Answered by AI
  • Q5. What is Async/Await ?
  • Ans. 

    Async/Await is a feature in JavaScript that allows for asynchronous programming using promises.

    • Async/Await is syntactic sugar built on top of promises in JavaScript.

    • It allows for writing asynchronous code that looks synchronous, making it easier to read and maintain.

    • Async functions return a promise, which allows for chaining multiple asynchronous operations.

    • Await keyword is used inside async functions to wait for a pro...

  • Q2. Difference Between RestApi and Graphql ?
  • Ans. 

    REST API is a standard protocol for web services using HTTP, while GraphQL is a query language for APIs.

    • REST API follows a client-server architecture with stateless communication, while GraphQL allows clients to request only the data they need.

    • REST API typically uses multiple endpoints for different resources, while GraphQL uses a single endpoint for flexible data retrieval.

    • REST API has predefined data structures, whil...

    • Common CORS middleware libraries include 'cors' in Node.js and 'django-cors-headers' in Django

  • Answered by AI
  • Q2. What is event loop in javascript?
  • Ans. 

    Event loop in JavaScript is a mechanism that allows asynchronous non-blocking code execution.

    • Event loop is responsible for handling asynchronous operations in JavaScript.

    • It continuously checks the call stack and the callback queue to see if there are any functions that need to be executed.

    • Event loop ensures that JavaScript remains single-threaded and non-blocking.

    • Example: setTimeout() function in JavaScript uses the ev...
