Firebase - What is the difference between ref and child?

Question

In Firebase, ref and child are used a lot.

For example - firebase.database().ref(\'users/\') will work exactly same

Answer 1

There is no difference, in any case you have a DatabaseReference instance.

A Firebase reference represents a particular location in your Database and can be used for reading or writing data to that Database location.

The method:

public DatabaseReference getReference (String path)

Gets a DatabaseReference for the provided path.

The method:

public DatabaseReference child (String pathString)

Get a reference to location relative to this one.
