如何为具有多个字段的对象数组创建v模型

class ObjectModel {
  constructor(name, age, gender) {
    this.name = name;
    this.age = age;
    this.gender = gender;
  }
}

const objects = [
  new ObjectModel("John", 25, "Male"),
  new ObjectModel("Jane", 30, "Female"),
  new ObjectModel("Bob", 35, "Male")
];

class ViewModel {
  constructor(objects) {
    this.objects = objects;
  }
  
  getNames() {
    return this.objects.map(obj => obj.name);
  }
  
  getAges() {
    return this.objects.map(obj => obj.age);
  }
  
  getGenders() {
    return this.objects.map(obj => obj.gender);
  }
  
  // 其他操作和方法...
}

const viewModel = new ViewModel(objects);

const names = viewModel.getNames();
console.log(names); // 输出：["John", "Jane", "Bob"]

const ages = viewModel.getAges();
console.log(ages); // 输出：[25, 30, 35]

const genders = viewModel.getGenders();
console.log(genders); // 输出：["Male", "Female", "Male"]
