我如何解析来自firebase的数据并存储到各个变量

Question

  firebase.initializeApp(config);

     var database = firebase.database();
    var leadsRef = database.ref('messages');
    leadsRef.on('value', function(snapshot) {
    snapshot.forEach(function(childSnapshot) {
      var childData = childSnapshot.val();

       console.log(childData);   
    });
});

我收到以下输出

{activityCatagory: "immediate", company: "test", email: "test@gmail.com", github: "test", linkedin: "test", …}
