How to get city name from a latitude and longitude point with JavaScript?

To get city name from a latitude and longitude point with JavaScript, we use the MapQuest API.

For instance, we write

const fetchLocationName = async (lat, lng) => {
  const response = await fetch(
    "https://www.mapquestapi.com/geocoding/v1/reverse?key=API-Key&location=" +
      lat +
      "%2C" +
      lng +
      "&outFormat=json&thumbMaps=false"
  );
  const responseJson = await response.json();
  console.log(JSON.stringify(responseJson));
};

to make a get request to the MapQuest reverse geocoding URL with fetch with the lat latitude and lng longitude.

Then we call json to get the JSON response body from response.
