Round 1 - Video Call 

(4 Questions)

Round duration - 45 minutes
Round difficulty - Medium

Technical round with questions on Javascript mainly.

  • Q1. What happens when you call a function using the new keyword?
  • Ans. 

    Calling a function using the new keyword creates a new instance of the function's constructor.

    • Creates a new empty object

    • Binds 'this' to the new object

    • Adds a property to the new object called '__proto__' which points to the constructor function's prototype object

    • Returns the new object

  • Answered by AI
  • Q2. How can you import all exports of a file as an object in JavaScript?
  • Ans. 

    You can import all exports of a file as an object in JavaScript using the 'import * as' syntax.

    • Use the 'import * as' syntax followed by the object name and 'from' keyword to import all exports of a file as an object.

    • For example: import * as myExports from './myFile.js';

    • You can then access the exports using dot notation, like myExports.myFunction().

  • Answered by AI
  • Q3. What is the purpose of the 'this' operator in JavaScript?
  • Ans. 

    The 'this' operator in JavaScript refers to the current context or object.

    • Refers to the current object or context in which a function is being executed

    • Can be used to access properties and methods of the current object

    • The value of 'this' is determined by how a function is called

  • Answered by AI
  • Q4. What are arrow functions in JavaScript?
  • Ans. 

    Arrow functions are a concise way to write functions in JavaScript.

    • Arrow functions are defined using the '=>' syntax.

    • They have a shorter syntax compared to traditional function expressions.

    • They do not have their own 'this' keyword, instead they inherit it from the parent scope.

    • Example: const add = (a, b) => a + b;

    Observables are streams that can emit multiple values over time, while promises can only emit a single value.

    • Observables can emit multiple values over time, while promises can only emit a single value.

    • Observables are cancellable, while promises are not.
