如何降低此javascript时间戳构建器函数的复杂性/嵌套if

// 使用箭头函数和解构赋值简化代码
const buildTimestamp = () => {
  const currentDate = new Date();
  const year = currentDate.getFullYear();
  const month = currentDate.getMonth() + 1;
  const day = currentDate.getDate();
  const hours = currentDate.getHours();
  const minutes = currentDate.getMinutes();
  const seconds = currentDate.getSeconds();

  // 使用条件运算符替代嵌套的if语句
  const formattedMonth = month < 10 ? `0${month}` : month;
  const formattedDay = day < 10 ? `0${day}` : day;
  const formattedHours = hours < 10 ? `0${hours}` : hours;
  const formattedMinutes = minutes < 10 ? `0${minutes}` : minutes;
  const formattedSeconds = seconds < 10 ? `0${seconds}` : seconds;

  // 返回格式化后的时间戳字符串
  return `${year}-${formattedMonth}-${formattedDay} ${formattedHours}:${formattedMinutes}:${formattedSeconds}`;
};

// 调用函数获取时间戳
const timestamp = buildTimestamp();
console.log(timestamp);
