get all properties of a feature

Question

I want to get the properties of a feature. How can I do that? In the example below we can get one of the properties out like so feature.get('species'). How can we get all of them at once? This is a failure feature.get('properties')

It works for geometry like feature.geometry() but not for properties.

// Make a feature and set some properties.
var feature = ee.Feature(ee.Geometry.Point([-122.22599, 37.17605]))
  .set('genus', 'Sequoia').set('species', 'sempervirens');

// Get a property from the feature.
print(feature.get('species'));

print(feature.get('properties'));

Answer 1

//dictionary of property names and values
print(feature.toDictionary())

//or list of either property names or values
print(feature.toDictionary().keys())
print(feature.toDictionary().values())
