如何在react native中计算{dd-mm-yyyy}格式的两个日期之间的差异

// 导入所需的库
import React from 'react';
import { View, Text } from 'react-native';

// 计算日期差异的函数
const calculateDateDifference = (startDate, endDate) => {
  // 将日期字符串转换为Date对象
  const start = new Date(startDate);
  const end = new Date(endDate);

  // 计算日期差异（以天为单位）
  const differenceInTime = end.getTime() - start.getTime();
  const differenceInDays = differenceInTime / (1000 * 3600 * 24);

  return differenceInDays;
};

// 示例组件
const DateDifferenceComponent = () => {
  // 定义起始日期和结束日期
  const startDate = '01-01-2022';
  const endDate = '31-12-2022';

  // 调用计算日期差异的函数
  const differenceInDays = calculateDateDifference(startDate, endDate);

  return (
    <View>
      <Text>起始日期: {startDate}</Text>
      <Text>结束日期: {endDate}</Text>
      <Text>日期差异（天数）: {differenceInDays}</Text>
    </View>
  );
};

export default DateDifferenceComponent;
