firebase - Store files with unique/random names

Question

With the new Firebase API you can upload files into cloud storage from client code. The examples assume the file name is known or static during upload:

// Create a root reference
var storageRef = firebase.storage().ref();
    
// Create a reference to 'mountains.jpg'
var mountainsRef = storageRef.child('mountains.jpg');
    
// Create a reference to 'images/mountains.jpg'
var mountainImagesRef = storageRef.child('images/mountains.jpg');

or

// File or Blob, assume the file is called rivers.jpg
var file = ...
    
// Upload the file to the path 'images/rivers.jpg'
// We can use the 'name' property on the File API to get our file name
var uploadTask = storageRef.child('images/' + file.name).put(file);

With users uploading their own files, name conflicts are going to be an issue. How can you have Firebase create a filename instead of defining it yourself? Is there something like the push() feature in the database for creating unique storage references?
