lc['_event']['latitude'] Will get you to the lattitude and

lc['_event']['longitude'] Will get you to the longitude

For future reference, I would suggest you to Search: Javascript objects variables

or try: https://www.w3schools.com/js/js_variables.asp

If you are using Leaflet.Locate plugin, then simply refer to its documentation, which mentions that you can use Leaflet built-in location events:

You can leverage the native Leaflet events onlocationfound and onlocationerror to handle when geolocation is successful or produces an error. You can find out more about these events in the Leaflet documentation.

The linked tutorial provides you with a code snippet how to use the location found event to get the coordinates:

function onLocationFound(e) {
    var radius = e.accuracy; // Note: accuracy is already a radius

    L.marker(e.latlng).addTo(map)
        .bindPopup("You are within " + radius + " meters from this point").openPopup();

    L.circle(e.latlng, radius).addTo(map);
}

map.on('locationfound', onLocationFound);
