You could try something like this:

firebase.database().ref().once('value', function(snapshot) {
    if (snapshot.val() !== null) {
        var tableNames = Object.keys(snapshot.val());
        console.log(tableNames); // ["answers", "blocks", "chats", "classes"]
    }
});

So that gets that whole database and then gets the top level keys from the returned object.

In some cases you may want a snapshot of your data without listening for changes, such as when initializing a UI element that you don't expect to change. You can use the once() method to simplify this scenario: it triggers once and then does not trigger again.

The Object.keys() method returns an array of a given object's own enumerable properties
