You would think that sending HTTP requests is a basic capability, but I've had fun in many languages doing so. Long ago (2020, or not so long ago, depending on how you look at it) I was surprised that doing an HTTP request on node using no dependencies was a little awkward:

  const response = await new Promise( (resolve, reject) => {
    const req = https.request(url, {
    }, res => {
      let body = "";
      res.on("data", data => {
        body += data;
      });
      res.on('end', () => {
        resolve(body);
      });
    });
    req.end();
  });
