ViewsRealtime database query and react native
I'm quite new to performing firebase realtime database queries and react native. I have a list of users in my realtime database and some of the users have a list of properties as shown below. I would like to obtain these properties as well as the users of the properties and place it into an array using react native. I'm not to sure how to do this.
This is what I have so far:
database().ref(`users/`).once(`value`, snapshot =>{
snapshot.forEach(function(childSnapshot){
if(childSnapshot.val().properties != null) {
}
});
I would like the error to be displayed as:
[{uid1,property1}, {uid1,property2}, {uid2,property1}, {uid2,property2}, {uid2,property3},...., {uidX,propertyX}]
})

I find that in cases like this, it really helps to give your variables good names:
database().ref(`users/`).once(`value`, snapshot =>{
let properties = [];
snapshot.forEach((userSnapshot) => {
if (userSnapshot.hasChild("properties")) {
userSnapshot.child("properties").forEach((propertySnapshot) => {
properties.push({
uid: userSnapshot.key,
property: propertySnapshot.val()
})
})
}
});
console.log(properties);
});
