使用ES6或TypeScript在两个对象数组之间进行比较

const array1 = [{id: 1, name: 'John'}, {id: 2, name: 'Jane'}, {id: 3, name: 'Alice'}];
const array2 = [{id: 2, name: 'Jane'}, {id: 4, name: 'Bob'}, {id: 5, name: 'Tom'}];

const result = array1.filter(obj1 => !array2.some(obj2 => obj1.id === obj2.id));

console.log(result);
// Output: [{id: 1, name: 'John'}, {id: 3, name: 'Alice'}]

const array1 = [{id: 1, name: 'John'}, {id: 2, name: 'Jane'}, {id: 3, name: 'Alice'}];
const array2 = [{id: 2, name: 'Jane'}, {id: 4, name: 'Bob'}, {id: 5, name: 'Tom'}];

const result = array1.reduce((acc, obj1) => {
  if (!array2.some(obj2 => obj1.id === obj2.id)) {
    acc.push(obj1);
  }
  return acc;
}, []);

console.log(result);
// Output: [{id: 1, name: 'John'}, {id: 3, name: 'Alice'}]

const _ = require('lodash');

const array1 = [{id: 1, name: 'John'}, {id: 2, name: 'Jane'}, {id: 3, name: 'Alice'}];
const array2 = [{id: 2, name: 'Jane'}, {id: 4, name: 'Bob'}, {id: 5, name: 'Tom'}];

const result = _.differenceBy(array1, array2, 'id');

console.log(result);
// Output: [{id: 1, name: 'John'}, {id: 3, name: 'Alice'}]
