javascript - 基于javascript中的另一个数组过滤对象数组

Question

给定一个对象数组:

people = [
    {id: "1", name: "abc", gender: "m", age:"15" },
    {id: "2", name: "a", gender: "m", age:"25" },
    {id: "3", name: "efg", gender: "f", age:"5" },
    {id: "4", name: "hjk", gender: "m", age:"35" },
    {id: "5", name: "ikly", gender: "m", age:"41" },
    {id: "6", name: "ert", gender: "f", age:" 30" },
    {id: "7", name: "qwe", gender: "f", age:" 31" },
    {id: "8", name: "bdd", gender: "m", age:" 78" },
]

还有一组想要的 ids:

id_filter = [1,4,5,8]

如何过滤数组 people 以返回 id_filter 和 gender=m 中定义的目标 ID？

Answer 1

最简单的过滤方式是使用数组的filter()功能，类似于:

people.filter(person => id_filter.includes(person.id))
