| Inheritance | DataSnapshot  Object |
A DataSnapshot instance contains data from a Firebase Database location. Any time you read Database data, you receive the data as a DataSnapshot.
They are efficiently-generated immutable copies of the data at a Firebase
Database location. They can't be modified and will never change. To modify
data at a location, use a DatabaseReference reference
(e.g. with setValue()).
