Ques:- What are promises and async await in JavaScript
Right Answer:
Promises in JavaScript are objects that represent the eventual completion (or failure) of an asynchronous operation and its resulting value. They allow you to handle asynchronous code more easily by providing methods like `.then()` for success and `.catch()` for errors.

`async` and `await` are syntactic sugar built on top of promises. An `async` function always returns a promise, and within an `async` function, you can use `await` to pause execution until a promise is resolved, making the code easier to read and write as if it were synchronous.
Ques:- What is JavaScript and how is it used in web development
Right Answer:
JavaScript is a programming language used to create interactive and dynamic content on websites. It allows developers to manipulate HTML and CSS, handle events, and communicate with servers, enhancing user experience and functionality in web development.
