<script>
  // 初始化Firebase
  const firebaseConfig = {
    apiKey: "YOUR_API_KEY",
    authDomain: "YOUR_AUTH_DOMAIN",
    databaseURL: "YOUR_DATABASE_URL",
    projectId: "YOUR_PROJECT_ID",
    storageBucket: "YOUR_STORAGE_BUCKET",
    messagingSenderId: "YOUR_MESSAGING_SENDER_ID",
    appId: "YOUR_APP_ID"
  };

  firebase.initializeApp(firebaseConfig);
</script>

const users = [
  { name: "Alice", age: 25 },
  { name: "Bob", age: 30 },
  { name: "Charlie", age: 35 }
];

const usersRef = firebase.database().ref("users");

users.forEach(user => {
  usersRef.push(user);
});

const usersRef = firebase.database().ref("users");

usersRef.on("value", snapshot => {
  const users = [];

  snapshot.forEach(childSnapshot => {
    const user = childSnapshot.val();
    users.push(user);
  });

  console.log(users);
});
