xmlHttp.setRequestHeader("Accept", "application/vnd.github.v3+json");
xmlHttp.send( null );
console.log(xmlHttp.responseText);

      "Authorization": token,
      "User-Agent": "v2FilteredStreamJS"
    }
  })
  .then(res => res.json())
  .then(data => {
    console.log(data);
  })
  .catch(err => {
    console.error(err);
  });

Example 3: Retrieve Weather Information from OpenWeatherMap
