Javascript -仅保留给定的所需属性列表的值

function filterProperties(obj, properties) {
  let result = {};
  for (let property of properties) {
    if (obj.hasOwnProperty(property)) {
      result[property] = obj[property];
    }
  }
  return result;
}

// 示例用法
let person = {
  name: 'John',
  age: 30,
  gender: 'male',
  occupation: 'developer',
};

let desiredProperties = ['name', 'age'];
let filteredPerson = filterProperties(person, desiredProperties);
console.log(filteredPerson);
// 输出: { name: 'John', age: 30 }
