javascript - 在 JavaScript 中访问 JSON 对象(已解析)中的数据

Question

我需要从这个 JSON 对象中获取数据“消息”。我怎样才能在 JavaScript 中做到这一点？

要访问我刚刚使用的姓氏:

response[i].user.lastname

但是我怎样才能访问消息呢？

[
    {
        "user": {
            "last_message": {
                "message": {
                    "created_at": "2011-04-16T16:40:56Z",
                    "updated_at": "2011-04-16T16:40:56Z",
                    "to": null,
                    "id": 10,
                    "user_id": 28,
                    "message": "This is a message"
                }
            },
            "nickname": "thenicky",
            "id": 28,
            "lastname": "white",
            "firstname": "Sean",
            "bio": "A short bio",
            "email": "the@email.com"
        }
    }
]
