To give the completed code a quick test-drive:

1. Install Node.js
2. Navigate to the project folder and run the following from a terminal:
   • npm init -y (to create a Node.js project)
   • npm i express (to install Express)
   • node server.js (to run the server)
3. Open localhost in a web browser, using the port specified in server.js e.g. http://localhost:3000/

Refer to the YouTube Tutorial for step-by-step instructions to create the code. Enjoy! :)
