Q1. What is Node JS?
Ans. 
Node.js is a runtime environment that allows you to run JavaScript code outside of a web browser.
• Node.js is built on Chrome's V8 JavaScript engine.

• It uses an event-driven, non-blocking I/O model that makes it lightweight and efficient.

Q2. What is Event Loop?
Ans. 
Event Loop is a mechanism that allows JavaScript to perform non-blocking operations by handling asynchronous tasks.
• Event Loop is a part of JavaScript runtime that continuously checks the call stack and the callback queue.

• It processes tasks in the callback queue only when the call stack is empty.

• Event Loop helps in handling asynchronous operations like setTimeout, AJAX requests, and event listeners.
