i need help

This code should create a sequence of div elements that each hold a headline above and a link below. Currently only the headlines display, and the links do not. Can you figure out how to fix this to make the links display under each headline?

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>

If you look at the code on line 23 that adds the header, you will see an example that is very similar to what you need to do to add the link.

The code on line 23 appends the header element to the div element.

To "make the links display", you need to add a line of code that will append the link element to the div.
