From what I understand you are trying to access the keys (UUIDs) of the children dataSnapshots of the parent dataSnapshot .

If this is what you want to do, then try like this:

const chatRoomRef = database().ref(firebaseMessages.CHAT_ROOM);

chatRoomRef.once('value').then(snapshot => {

//loop through the children here

snapshot.forEach((child) => {

//print the key or UUID of each child

console.log('User data: ', child.key);

});

});
