如何在两个日期之间找到最先到达的日期

function findEarliestDate(date1, date2) {
  var earliestDate;

  if (date1 < date2) {
    earliestDate = date1;
  } else if (date1 > date2) {
    earliestDate = date2;
  } else {
    earliestDate = "两个日期相等";
  }

  return earliestDate;
}

var date1 = new Date("2022-01-01");
var date2 = new Date("2022-01-02");
var earliestDate = findEarliestDate(date1, date2);
console.log("最先到达的日期是：" + earliestDate);
