js中对多维数组进行过滤和排序

Question

在 JavaScript 中给出以下数组：

_articles = [{ id: 0, name: 'aaa', category: 1, date: '2021-05-17'}, { id: 1, name: 'bbb', category: 3, date: '2021-03-15'}, { id: 0, name: 'ccc', category: 2, date: '2021-02-11'}, { id: 0, name: 'ddd', category: 1, date: '2021-04-11'}]

如何按类别=2过滤并按日期排序（最近优先）？

Answer 1

您必须使用filter 和sort

let filtered = _articles.filter(x=> x.category=2)

和排序DESC

let sorted =_articles.sort((a,b) => new Date(b.date)-new Date(a.date))
