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;
