Completely stumped on this challenge. I have found a solution but the program said it is not the 'right' way to do it. Please help I spent 2 hours on this problem and I cannot find a way around it.
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.lastElementChild;
//div.insertBefore(link, h2);
//h2.appendChild(link);
// end
return div;
}
for (let i = 0; i < languages.length; i += 1) {
let div = createDiv(languages[i]);
section.appendChild(div);
}

Front End Web Development Techdegree Graduate 84,738 PointsWhat you want is:
div.appendChild(link);
The goal is to create a structure like this for each language:
<div>
<h2>Python</h2>
<a href="'https://wikipedia.org/wiki/Python_(programming_language)"><p>Information about Python</p></a>
</div>
So far they've given us this:
1) We create some empty <div>
, <h2>
, <p>
elements:
const div = document.createElement('div');
const h2 = document.createElement('h2');
const p = document.createElement('p');
2) We create the <a>
element using the linkify
function defined earlier and the name of the language:
const link = linkify(language); // this will make <a href="'https://wikipedia.org/wiki/Python_(programming_language)"></a>
3) We've filedl the contents of the <h2>
with the language name.
h2.textContent = language; // this will make <h2>Python</h2>
4) We've filled the contents of the <p>
with the language name and text
p.textContent = 'Information about ' + language; // this will make <p>Information about Python</p>
5) We've stuck the <p>
element inside the <a>
element:
link.appendChild(p); // this will make <a href="'https://wikipedia.org/wiki/Python_(programming_language)"><p>Information about Python</p></a>
6) We've stuck the <h2>
element inside the <div>
:
div.appendChild(h2);
So now we have:
<div>
<h2>Python</h2>
</div>
So now we just need to finish it off, and stick the link
variable, which has the <a>
with the <p>
inside it, inside the <div>
as well:
div.appendChild(link);
