used: div.append(link); Preview looks correct, but shows up wrong?

div.append(link);

on line 27 should append all the links to the div element. And it looks correct on the preview but it saids it's wrong. with the error message (div.append(link);) is undefined?

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

  div.append(link);
  // end

  return div;
}

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

  section.appendChild(div);
}

So a little bit of google and I found the answer.

.append() is a jquery method. Using the plain javascript function .appendChild(); got it to pass.
