// A global power plant FeatureCollection.
var fc = ee.FeatureCollection('WRI/GPPD/power_plants');
// View a list of FeatureCollection property names.
print(fc.propertyNames());
// Get the value of a listed property.
print('Global power plant data provider as ee.ComputedObject',
fc.get('provider'));
// The returned value is an ee.ComputedObject which has no methods available for
// further processing; cast to the relevant Earth Engine object class for use.
print('Global power plant data provider as ee.String',
ee.String(fc.get('provider')));
