使用Lodash查找新添加的对象数组元素

const _ = require('lodash');

// 假设我们有两个对象数组
const oldArray = [
  { id: 1, name: 'Apple' },
  { id: 2, name: 'Banana' },
  { id: 3, name: 'Orange' }
];

const newArray = [
  { id: 1, name: 'Apple' },
  { id: 2, name: 'Banana' },
  { id: 3, name: 'Orange' },
  { id: 4, name: 'Grape' }
];

// 使用_.differenceBy函数查找新添加的对象数组元素
const addedElements = _.differenceBy(newArray, oldArray, 'id');

console.log(addedElements);
