比较2个数组的对象并找到匹配的颜色id，然后创建一个新的数组Javascript

const matchingObjects = array1.filter(obj1 => {
  return array2.some(obj2 => obj2.colorId === obj1.colorId);
});

const matchingColorIds = matchingObjects.map(obj => obj.colorId);

const array1 = [
  { colorId: 1, name: 'Red' },
  { colorId: 2, name: 'Blue' },
  { colorId: 3, name: 'Green' }
];

const array2 = [
  { colorId: 2, name: 'Blue' },
  { colorId: 4, name: 'Yellow' },
  { colorId: 1, name: 'Red' }
];

const matchingObjects = array1.filter(obj1 => {
  return array2.some(obj2 => obj2.colorId === obj1.colorId);
});

const matchingColorIds = matchingObjects.map(obj => obj.colorId);

console.log(matchingColorIds); // 输出 [1, 2]
