Javascript -如何在运行时动态创建对象？

function Person(name, age) {
  this.name = name;
  this.age = age;
}

var person = new Person("John", 25);
console.log(person.name); // 输出：John
console.log(person.age); // 输出：25

var person = {
  name: "John",
  age: 25
};

console.log(person.name); // 输出：John
console.log(person.age); // 输出：25

var person = {
  name: "John",
  age: 25
};

var newPerson = Object.create(person);
console.log(newPerson.name); // 输出：John
console.log(newPerson.age); // 输出：25

function createPerson(name, age) {
  return {
    name: name,
    age: age
  };
}

var person = createPerson("John", 25);
console.log(person.name); // 输出：John
console.log(person.age); // 输出：25
