根据其中的数组合并数组中的 javascript 个对象

Question

将数组重组为输出的最佳方法是什么？我需要将所有值键（无论是否为数组）合并到共享相同名称键的对象中。这里有类似的东西，但这不能回答我的问题，因为我也有数组。

var array = [{
  VULN: [{random1:"asd11",random2:"asd12"}, {random3:"asd23",random4:"asd24"}]
}, {
  VULN: [{random5:"asd35",random6:"asd36"}, {random7:"asd47",random8:"asd43"}]
}, {
  VULN: [{random9:"asd55",random10:"asd51"}, {random11:"asd56",random12:"asd63"}]
}];

至

VULN=[{random1:"asd11",random2:"asd12"}, {random3:"asd23",random4:"asd24"},{name:"asd3",value:"asd3"}, {random5:"asd35",random6:"asd36"}, {random7:"asd47",random8:"asd43"}, {random9:"asd55",random10:"asd51"}, {random11:"asd56",random12:"asd63"}]

Answer 1

这是你想要的：

var array = [{
    VULN: [{ name: "asd1", value: "asd1" }, { name: "asd2", value: "asd2" }]
}, {
    VULN: [{ name: "asd3", value: "asd3" }, { name: "asd4", value: "asd4" }]
}, {
    VULN: [{ name: "asd5", value: "asd5" }, { name: "asd6", value: "asd6" }]
}];

console.log(array.map(x => x.VULN).flat())

Answer 2

使用flatMap:

array.flatMap(x => x.VULN);

Answer 3

使用lodash

lodash.flatten(array.map(x => x.VULN))
