使用chat GPT 生成一个js 生成天数的方法

function calculateDaysDifference(targetDateString) {
  
  const currentDate = new Date();
  const targetDate = new Date(targetDateString);
  
  // 计算毫秒差异
  const timeDifference = targetDate - currentDate;
  
  // 计算天数差异，如果结果为负数，则设置为0
  const daysDifference = Math.max(Math.floor(timeDifference / (1000 * 60 * 60 * 24)), 0);
  
  // 计算小时差异，如果结果为负数，则设置为0
  const hoursDifference = Math.max(Math.floor((timeDifference % (1000 * 60 * 60 * 24)) / (1000 * 60 * 60)), 0);
  
  // 计算分钟差异，如果结果为负数，则设置为0
  const minutesDifference = Math.max(Math.floor((timeDifference % (1000 * 60 * 60)) / (1000 * 60)), 0);

  return {
    days: daysDifference,
    hours: hoursDifference,
    minutes: minutesDifference
  };
}
