In this course, you’ll learn how to build a full-stack application using the MEAN stack. You’ll begin with the frontend by learning how to create and set up an Angular application from scratch. Furthermore, you’ll learn to implement routing, router guards, token-based authentication, authorization, error handling, and dependency Injection in an Angular application.

Next, the focus shifts to the backend. You’ll learn by using Node.js, Express, and MongoDB to create REST APIs. Additionally, you’ll learn to create middleware for handling errors, token verification, setting up models and schemas, creating a database using MongoDB, as well as the concept of separation of concern.

By the end of this course, you will have an understanding of how to connect both the backend and the frontend together to create a full-stack application, as well as how to deploy a fully functional application.

Building a Full-stack Application Using the MEAN Stack

# Explanation
* We start by requiring the built-in `HTTP` module in **line 1**.

* In **line 3**, we create a variable called `server`. This variable holds the logic for the `createServer()` method that enables us to create an HTTP server that gives a response back to the client. This is made possible by two methods: the `res.writeHead()` method and the `res.end()` method.

* The `res.writeHead()` method helps us to set the correct content type of 'text/html'. This allows us to display `HTML` elements on the page.

* In **line 6**, the `res.end()` method takes in the `HTML` tags to be displayed on the browser and helps us end the response process.
  
* Finally, in **line 20**, we chain our function using the `listen()` method to work on port `5000`.
