Thanks for watching!
P.S. Bonus for description readers: there is another way to build a web app without Sinatra, or Rack, or without having to build a web server.
That way is to use an ANCIENT technology called CGI. It's implemented at the web server level (Apache/Nginx) & it allows you to link a Ruby script with web server requests.
You'll need to print the HTTP headers & then your content, similar to what Rack does.
