<body>
  <script>
    const dataset = [12, 31, 22, 17, 25, 18, 29, 14, 9];

    d3.select('body')
      .selectAll('h2')
      .data(dataset)
      .enter()
      .append('h2')
      .text(d => d + ' USD');
    // Add your code below this line
      .style('font-family', 'verdana');

    // Add your code above this line
  </script>
</body>

nothing wrong with my code, but console give me this error:

SyntaxError: unknown: Unexpected token (11:6)

   9 |       .text(d => d + ' USD');
  10 |     // Add your code below this line
> 11 |       .style('font-family', 'verdana');
     |       ^
  12 |
  13 |
  14 |     // Add your code above this line

After further inspecting the code, I found that I have to remove “;” from line code above
the comment “// Add your code below this line”

my final code:

<body>
  <script>
    const dataset = [12, 31, 22, 17, 25, 18, 29, 14, 9];

    d3.select('body')
      .selectAll('h2')
      .data(dataset)
      .enter()
      .append('h2')
      .text(d => d + ' USD')
    // Add your code below this line
      .style('font-family', 'verdana');

    // Add your code above this line
  </script>
</body>

it’s pretty confusing for 5 minutes struggling to finish this.
