DOM Scripting by example.

Can someone point be in the right direction for this challenge. It says one line of code is necessary; however, i don't understand why the missing line is preventing the divs to display on screen

app.js 
const languages = ['Python', 'JavaScript', 'PHP', 'Ruby', 'Java', 'C'];
const section = document.getElementsByTagName('section')[0];

// Accepts a language name and returns a wikipedia link
function linkify(language) {
  const a = document.createElement('a');
  const url = 'https://wikipedia.org/wiki/' + language + '_(programming_language)';
  a.href = url;
  return a;
}

// Creates and returns a div
function createDiv(language) {
  const div = document.createElement('div');
  const h2 = document.createElement('h2');
  const p = document.createElement('p');
  const link = linkify(language);

  h2.textContent = language;
  p.textContent = 'Information about ' + language;
  link.appendChild(p);

  div.appendChild(h2);

  // Your code below


  // end

  return div;
}

for (let i = 0; i < languages.length; i += 1) {
  let div = createDiv(languages[i]);

  section.appendChild(div);
}
index.html 
<!DOCTYPE html>
<html>
<head>
  <title>Programming Languages</title>
  <style>
    body {
      font-family: sans-serif;
    }
  </style>
</head>
<body>
  <h1>Programming Languages</h1>
  <section></section>
  <script src="app.js"></script>
</body>
</html>

The question includes the text "This code should create a sequence of div elements that each hold a headline above and a link below.". Look for the code related to getting heading onto the page. Look for the code related to link and think "what is missing?". (you asked me to point you in the right direction rather than just post the answer. If you want more, just specify. If you just want the answer, then try https://teamtreehouse.com/community/this-code-should-create-a-sequence-of-div-elements-that-each-hold-a-headline-above-and-a-link-below-currently-only-the-4 )
