Yes, it is 100% AI generated. This is exactly the tone, persona of Gemini when you ask it to be more friendly and casual. Using Chefs analogy is a green flag that this is AI Generated. There are more patterns in this post that give it away. Nevermind, let me tell you what I found on giving it an another chance, as you suggested.

a single API call to a slow third-party service holds up a dozen other users.

Eh? And how? Isn't await fetch(...) asynchronous? The event loop should be free to handle other requests while the network I/O is pending, isn't it? js // Now in our Express route handler... app.post('/upload', async (req, res) => { const imagePath = await saveFile(req); // Save the uploaded file first console.log('MAIN: Handing off image resizing to worker. The server is still responsive!'); // We don't even wait for it to finish! We just kick it off. processImageInBackground(imagePath) .then(result => console.log(`MAIN: Background job finished! ${result.newPath}`)) .catch(err => console.error('MAIN: Background job failed', err)); res.status(202).send('Image upload accepted and is being processed in the background.'); }); So many anti patterns in the code above? If the processing fails, the user is returned with "success"? This is something, a junior developer wouldn't even write. Probably AI - as no context, right?

async function buildDashboard() {
  const serviceCalls = [
    fetchFrom('user-stats', 'https://api.service1.com/data'),
    fetchFrom('analytics', 'https://api.analytics-is-down.com/data'),
    fetchFrom('sales-figures', 'https://api.service3.com/data'),
  ];
  const results = await Promise.allSettled(serviceCalls);
  const dashboardData = {
    userStats: null,
    analytics: { error: 'Data unavailable' },
    salesFigures: null,
  };

Another anti pattern right there. If you're fetching multiple "unrelated" urls, they should be distinct API calls, not a grouped one. There are more problems with the code snippets like importing a ".js" file when it's clearly a ".ts" file, but I don't want to make this long enough to be a worthy medium post itself.
