// 请将 AppId 改为你自己的 AppId，否则无法本地测试

    });

  await room.send (new AV.TextMessage ('1'));
  await room.send (new AV.TextMessage ('2'));
  await room.send (new AV.TextMessage ('3'));
}

init ().catch (function (err) {
  console.error (err);
});

简单的创建聊天室+发送信息
但是

 conversation.on ('MESSAGE', function (message) {
        console.log (message);
      });

conversation没有监听成功！！！！！？？？？

带来来着 js的聊天室demo
