HTML generation via test server in JavaScript

Test server handlers can also send HTML code:

server.jsexport default {
  '/test/': function() {
    return '<b>text</b>';
  }
}

You can also generate HTML code in a loop:

server.jsexport default {
  '/test/': function() {
    let str = '<ul>';
    
    for (let i = 1; i < 9; i ++) {
      str += '<li>' + i + '</li>';
    }
    
    str += '</ul>';
    
    return str;
  }
}

Let an array be given on the server:

server.jslet arr = [1, 2, 3, 4, 5];

Make a route that writes each element of the array into its own paragraph and sends the result to the server.
