Javascript 使用Google Apps脚本为评估之间的日期调整文件创建日期值

我想查看文件创建日期，而不是当前日期，并添加6天，以便我的中间代码能够正常工作

var dateFrom = file.getDateCreated();
var dateTo = new Date();

dateTo.setDate(dateTo.getDate() + 6).toString();

var dateCheck = new Date();

dateCheck.setDate(dateCheck.getDate()).toString();

var from = Date.parse(dateFrom);
var to   = Date.parse(dateTo);
var check = Date.parse(dateCheck );

if((check <= to && check >= from))      
    //  alert("do something");

我希望有人能帮助我学会如何找到成功。 当做

此代码确定今天的日期是在目标日期还是超过目标日期。目标日期比文件创建日期晚6天：

function olderThan() {
  var file = DriveApp.getFileById('Your file ID');
  var myFileDate = file.getDateCreated();
  var creationDate = new Date(myFileDate);

  var now = new Date();
  var dateTo = new Date();
  dateTo.setDate(creationDate.getDate() + 6);

  if (now >= dateTo) {
    Logger.log('its older than 6 days old');
  };
};

function olderThan() {
  var file = DriveApp.getFileById('Your file ID');
  var myFileDate = file.getDateCreated();
  var creationDate = new Date(myFileDate);

  var now = new Date();
  var dateTo = new Date();
  dateTo.setDate(creationDate.getDate() + 6);

  if (now >= dateTo) {
    Logger.log('its older than 6 days old');
  };
};
