1. Create a new file named debugging.js
2. Initialize a new ExpressJS application:

      const express = require('express') 
      const app = express() 

3. Add a route method to handle GET requests for any path:

      app.get('*', (request, response, next) => { 
          response.send('Hello there!') 
      }) 

4. Listen on port 1337 for new connections:

      app.listen( 
          1337, 
          () => console.log('Web Server running on port 1337'), 
      ) 

5. Save the file
6. Open a terminal and run:
7. On Windows:

      set DEBUG=express:* node debugging.js

8. On Linux or MacOS:

      DEBUG=express:* node debugging.js 

9. In your web browser, navigate to:

      http://localhost:1337/
