JavaScript，谷歌工作表脚本-日期比较问题

var date1 = new Date('2022-01-01');
var date2 = new Date('2022-02-01');

if (date1.getTime() < date2.getTime()) {
  console.log('date1 is before date2');
} else if (date1.getTime() > date2.getTime()) {
  console.log('date1 is after date2');
} else {
  console.log('date1 is equal to date2');
}

var sheet = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet();
var date1 = sheet.getRange('A1').getValue();
var date2 = sheet.getRange('A2').getValue();

if (date1 < date2) {
  console.log('A1 is before A2');
} else if (date1 > date2) {
  console.log('A1 is after A2');
} else {
  console.log('A1 is equal to A2');
}
