# Node.js Basics

## Introduction

This project demonstrates the basic concepts of **Node.js**.
Node.js is a runtime environment that allows JavaScript to run on the server side.

Node.js allows developers to use JavaScript for backend development.
It is built on Chrome’s V8 engine and is used to create fast and scalable applications.

});

server.listen(3000, () => {
  console.log("Server is running on port 3000");
});
```
