    lat: 1.425255
  }
];

const fetch = function (term, cb) {
  //We only want to fetch if it's not current location, so check for lat
  if (!term.lat) {
    var matches = db.filter(function (item) {
    return (item.displayName + '').toLowerCase().indexOf(term.toLowerCase()) !== -1;
    });

    // mimic ajax
    setTimeout(function () {
      cb(matches);
    }, 50);
  }
};

// Instantiate a component, pass the selector of the container to insert component into and the opts
const locationSearch = new UI.LocationTypeahead('.location-search', fetch, {
  currentLocationText: 'Use my location',
  geolocationAPI: window.navigator.geolocation,
  textInputOpts: {
    placeholder: 'Try "New York"'

// Subscribe to when new choices are selected from the Typeahead
locationSearch.subscribe((choice) => {
  if (choice.isLocation) {
    console.log('location chosen', choice);
  } else {
    console.log(choice); // misc message
  }
});
