How to Get Geolocation Information in a Javascript/Typescript Program

Javascript snippet:

var options = {
  enableHighAccuracy: true,
  timeout: 5000,
  maximumAge: 0
};

function success(pos) {
  var crd = pos.coords;

  console.log('Your current position is:');
  console.log('Latitude : ' + crd.latitude);
  console.log('Longitude: ' + crd.longitude);
  console.log('More or less ' + crd.accuracy + ' meters.');
};

function error(err) {
  console.warn('ERROR(' + err.code + '): ' + err.message);
};

navigator.geolocation.getCurrentPosition(success, error, options);

Typescript snippet:

navigator.geolocation.getCurrentPosition(pos => {
  const lat = pos.coords.latitude.toFixed(6);  // latitude in degree
  const lng = pos.coords.longitude.toFixed(6); // longitude in degree
  ...
}, err => {
  console.warn('ERROR(' + err.code + '): ' + err.message);
}, {
  enableHighAccuracy: true,
  timeout: 5000,
  maximumAge: 0
});
