javascript - 两个对象数组与 lodash 的区别

Question

我在 reactJS 中的 useEffect 中有以下代码

const A1 = [{id: 1, nome: "Ruan"}, {id: 2, nome: "Gleison"}]
const A2 = [{id: 2, nome: "Gleison"}, {id: 3, nome: "Geraldo"}]

const results = _.xor(A1, A2);

console.log(results)

lodash 的逻辑是_.xor 是返回两个数组之间的差异，然而，这不是正在发生的事情

我得到的返回如下

0: Object {id: 1, nome: "Ruan"}
1: Object {id: 2, nome: "Gleison"}
2: Object {id: 2, nome: "Gleison"}
3: Object {id: 3, nome: "Geraldo"}

我感谢所有的帮助

您可以使用xorBy 来指示用于比较的属性:

const A1 = [{id: 1, nome: "Ruan"}, {id: 2, nome: "Gleison"}]
const A2 = [{id: 2, nome: "Gleison"}, {id: 3, nome: "Geraldo"}]

const results = _.xorBy(A1, A2, 'id'); // or 'nome'

console.log(results)
