HTML site

The topic is yours. Try to do it all from memory

  1. Create a basic app with multiple routes

  2. When it comes time to do res.send, instead of just text, send html

  3. To get res.send to work with line breaks in the html, change single/double quotes to backticks

     res.send(`
     <html>
         <body>
             <h1>Oh ha!</h1>
         </body>
     </html>
 `);
