javascript - Lodash:差异函数，但基于 JSON 格式

Question

var b = ["text1", "text2"];
var a = [
    {name: "text3", value: 2}, 
    {name: "text4", value: 7}, 
    {name: "text1", value: 4}
];

我尝试过多种Lodash函数，但没有一个返回我想要实现的目标。

我想要的是:

var c = ["text1"]; // uniques from a compared to b
var d = [
    {name: "text3", value: 2}, 
    {name: "text4", value: 7}
]; // uniques from b compared to b

Answer 1

您可以过滤数组并推送不唯一的项目。

var b = ["text1", "text2"],
    a = [{ name: "text3", value: 2 }, { name: "text4", value: 7 }, { name: "text1", value: 4 }],
    c = [],
    d = a.filter(({ name }) => !b.includes(name) || !c.push(name));
  
console.log(c);
console.log(d);

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