expand_twitter_short_links.js

//Helper Function
function findFirstUrl(text) {
  const urlRegex = /https?:\/\/(www\.)?[-a-zA-Z0-9@:%._\+~#=]{1,256}\.[a-zA-Z0-9()]{1,6}\b([-a-zA-Z0-9()@:%_\+.~#?&//=]*)/g;
  const match = text.match(urlRegex);
  return match ? match[0] : null; // Return the first URL or null if none found
}

//First Way
function expandUrl(shortUrl) {
    return fetch(shortUrl, { method: 'GET' })
        .then(response => {
            return response.text().then((data) => {
                return data;
            }).catch((err) => {
                console.log(err);
            })             
        })
}
expandUrl('https://t.co/twitter').then((data) => {
	console.log(findFirstUrl(data));
});

//Second Way
async function expandUrl(shortUrl) {
    const response = await fetch(shortUrl);
    const data = await response.text();
    console.log(findFirstUrl(data));
}
expandUrl('https://t.co/twitter');

//Third Way
const shortUrls = ['https://t.co/twitter'];
const expandedUrls = [];
const fetchPromises = shortUrls.map(url => {
    return fetch(url)
        .then(response => response.text())
        .then(data => {
            expandedUrls.push(findFirstUrl(data));
        })
        .catch(error => console.error('Error:', error));
});

Promise.all(fetchPromises)
    .then(() => console.log(expandedUrls))
    .catch(error => console.error('Error:', error));
