JavaScript中多日期值比较与最早日期查找的最佳实践

// 假设 env.STICKER_THRESH 是一个数组，例如 [30, 40, 60]
const env = {
    STICKER_THRESH: [30, 40, 60]
};

const getEarliestRunout = (runout_dates = {}, dm1_type = '') => {
    try {
        const cur_year = new Date().getFullYear();
        // 原始逻辑中用于过滤的非优先级贴纸类型
        const non_priority_sticker = dm1_type == cur_year + 1 || dm1_type == cur_year ? 'dm1' : 'dm2';

        return Object.entries(runout_dates).reduce((earliest, obj) => {
            const key = obj[0].split('_')[0]; // 例如 'dm1', 'dm2', 'star'
            const value = obj[1]; // 对应的值对象，如 { under_30: "...", under_40: "..." }

            // 原始问题在于，这里只检查了 env.STICKER_THRESH[0] 对应的日期
            // 并且通过 key != non_priority_sticker 进行了过滤
            // 这可能导致其他阈值（如 under_40, under_60）的日期被忽略，
            // 或特定类型的日期（如 star_runouts）未被全面比较。
            if (value[`under_${env.STICKER_THRESH[0]}`] && key != non_priority_sticker) {
                const currentDate = new Date(value[`under_${env.STICKER_THRESH[0]}`]).getTime();
                return currentDate < earliest.val ? { val: currentDate, date: value[`under_${env.STICKER_THRESH[0]}`] } : { ...earliest };
            }
            return earliest;
        }, { val: Infinity, date: '' });
    } catch (e) {
        console.error(`ERROR :: util.getEarliestRunout: ${e} - ${new Date()}`);
        return { val: Infinity, date: '' };
    }
};

// 假设的输入数据结构
const priorityRunouts = { under_30: "2024-01-10", under_40: "2024-01-15", under_60: "2024-01-20" };
const nonPriorityRunouts = { under_30: "2024-02-01", under_40: "2024-02-05", under_60: "2024-02-10" };
const starRunouts = { under_30: "2024-01-05", under_40: "2024-01-08", under_60: "2024-01-12" };

const inputRunoutDates = {
    dm1_runouts: priorityRunouts,
    dm2_runouts: nonPriorityRunouts,
    star_runouts: starRunouts
};

// 调用示例
// const earliest_runout = getEarliestRunout(inputRunoutDates, 'some_dm1_type');
// console.log("Original method result:", earliest_runout);

// 假设 env.STICKER_THRESH 仍然可用，并包含所有需要检查的阈值
const env = {
