Javascript 更新ScriptProperty以避免检索重复的Twitter状态

我有兴趣写一个推特机器人来帮助当地滑雪胜地的一些朋友。我从Amit Agarwal那里找到了这本教程，它给了我足够的时间开始学习（自从我做了很多修改之后，我确实花了5分钟多的时间）。我在谷歌文档上托管脚本

首先我认为这是javascript（我的理解是google apps脚本使用javascript…），当我到目前为止遇到代码问题时，google搜索javascript之类的东西很有帮助，但是如果这不是javascript，请让我知道，这样我可以相应地更新标签

我以前没有使用javascript的经验，所以我很高兴它能真正工作。但我想看看我做得对不对

start

函数启动触发器，每隔30分钟启动一次

fetchTweets（）

函数。为了避免重复（我遇到的第一个错误）&可能被标记为垃圾邮件，我需要一种方法来确保我不会一次又一次地发布相同的tweet。在

start（）

函数中，初始

since\u id

值被分配：

ScriptProperties.setProperty("SINCE_TWITTER_ID",        "404251049889759234");

在

fetchTweet（）

函数中，我想我正在用以下语句更新此属性：

ScriptProperties.setProperty("SINCE_TWITTER_ID", lastID + '\n');

这是一个好方法吗？还是有更好/更可靠的方法？如果是这样，我如何确定它正在更新属性？（我可以检查日志文件，它似乎正在这样做，因此我可能只需要为记录器创建一个永久文本文件）

非常感谢您的帮助
