  • Ans. 

    Promises are objects representing the eventual completion or failure of an asynchronous operation.

    • Promises are used to handle asynchronous operations in JavaScript.

    • They can be in one of three states: pending, fulfilled, or rejected.

    • Promises can be chained using .then() to handle success and .catch() to handle errors.

    • Example: fetch() API returns a promise that resolves with the response to a request.

    • Inheritance allows for code reuse and promotes the concept of hierarchy.

    • The class that is being inherited from is called the superclass or base class.

    • The class that inherits from the superclass is called the subclass or derived class.

    • The subclass can access the public and protected members of the s...

  • Q4. What is Abstraction
  • Ans. 

    Abstraction is the process of simplifying complex systems by focusing on essential details.

    • Abstraction involves hiding unnecessary details and exposing only relevant information.

    • It allows developers to create models or representations that capture the essential aspects of a system.

    • Abstraction helps in managing complexity, improving code reusability, and enhancing maintainability.

    Polymorphism is the ability of an object to take on many forms. It allows objects of different classes to be treated as the same type.

    • Polymorphism is a fundamental concept in object-oriented programming.

    • It enables code reusability and flexibility.

    • Polymorphism can be achieved through method overriding and method overloading.

    • Example: A parent class Animal can have multiple child classes like Dog, Cat, and Bird. They can ...

  • Q2. What is async and await
  • Ans. 

    Async and await are keywords in JavaScript used to work with asynchronous code.

    • Async is used to define a function as asynchronous, allowing it to run in the background without blocking the main thread.

    • Await is used to pause the execution of an async function until a Promise is settled, and then resumes the function with the resolved value.
