根据数组的顺序过滤对象属性

function filterObjectByOrder(obj, orderArray) {
  const filteredObj = {};
  orderArray.forEach((key) => {
    if (obj.hasOwnProperty(key)) {
      filteredObj[key] = obj[key];
    }
  });
  return filteredObj;
}

// 示例对象
const person = {
  name: 'John',
  age: 30,
  gender: 'Male',
  occupation: 'Engineer'
};

// 属性顺序数组
const orderArray = ['name', 'age', 'gender'];

// 过滤对象属性
const filteredPerson = filterObjectByOrder(person, orderArray);

console.log(filteredPerson);
// 输出: { name: 'John', age: 30, gender: 'Male' }
