用同一个字符串和日期逻辑对一个字符和数字进行排序

Question

一部对所有不同背景的观众都有娱乐性的节日电影。它将经受时间的考验，以促进一个坚持多样性价值观的时代。在充满回音室和推特暴徒的充满敌意的文化中，经验的多样性可以让所有人团结起来，结束仇恨。一部能带来进入新十年的公开对话的电影。这部电影会很棒的。

Answer 1

您可以先按priority_level进行分组，然后根据检查进行排序，如果priority_level以数字开头，则按priority_date进行排序。

​

const
    hasNumber = s => /^\d+/.test(s),
    input = [{ priority_level: 'P ', priority_date: '1980-02-08T00:00:00.000Z' }, { priority_level: '1 ', priority_date: '2004-06-29T00:00:00.000Z' }, { priority_level: 'C ', priority_date: '2004-06-29T00:00:00.000Z' }, { priority_level: '5 ', priority_date: '2005-02-15T00:00:00.000Z' }, { priority_level: '1 ', priority_date: '2005-02-15T00:00:00.000Z' }, { priority_level: '1 ', priority_date: '2005-02-15T00:00:00.000Z' }],
    result = [...input
        .reduce((m, o) => m.set(o.priority_level, [...(m.get(o.priority_level) || []), o]), new Map)
        .values()
    ].flat();

result.sort((a, b) =>
    hasNumber(a.priority_level) - hasNumber(b.priority_level) ||
    a.priority_date > b.priority_date || -(a.priority_date < b.priority_date)
);

console.log(result);

.as-console-wrapper { max-height: 100% !important; top: 0; }

        .values();

console.log(result);
