比较两个对象数组并返回item

function compareArrays(arr1, arr2) {
  let result = [];

  for (let obj1 of arr1) {
    for (let obj2 of arr2) {
      if (compareObjects(obj1, obj2)) {
        result.push(obj1);
        break;
      }
    }
  }

  return result;
}

function compareObjects(obj1, obj2) {
  // 比较对象的属性值
  for (let key in obj1) {
    if (obj1.hasOwnProperty(key) && obj2.hasOwnProperty(key)) {
      if (obj1[key] !== obj2[key]) {
        return false;
      }
    }
  }

  return true;
}

// 示例数据
let arr1 = [
  { id: 1, name: 'Apple' },
  { id: 2, name: 'Banana' },
  { id: 3, name: 'Orange' }
];

let arr2 = [
  { id: 2, name: 'Banana' },
  { id: 4, name: 'Grape' },
  { id: 5, name: 'Watermelon' }
];

// 比较两个对象数组并返回相同属性值的对象
let result = compareArrays(arr1, arr2);
console.log(result);

[
  { id: 2, name: 'Banana' }
]
