// Define a LinearRing object.
var linearRing = ee.Geometry.LinearRing(
    [[-122.091, 37.420],
     [-122.085, 37.422],
     [-122.080, 37.430]]);

// Apply the toGeoJSONString method to the LinearRing object.
var linearRingToGeoJSONString = linearRing.toGeoJSONString();

// Print the result to the console.
print('linearRing.toGeoJSONString(...) =', linearRingToGeoJSONString);

// Display relevant geometries on the map.
Map.setCenter(-122.085, 37.422, 15);
Map.addLayer(linearRing,
             {'color': 'black'},
             'Geometry [black]: linearRing');
