在Javascript中从对象创建对象

var obj = {
  property1: value1,
  property2: value2,
  method: function() {
    // 方法的实现
  }
};

function Person(name, age) {
  this.name = name;
  this.age = age;
  this.sayHello = function() {
    console.log("Hello, my name is " + this.name);
  };
}

var person = new Person("John", 25);
person.sayHello(); // 输出：Hello, my name is John

var parentObj = {
  property1: value1,
  method: function() {
    // 方法的实现
  }
};

var childObj = Object.create(parentObj);
childObj.property2 = value2;

function createPerson(name, age) {
  var obj = {};
  obj.name = name;
  obj.age = age;
  obj.sayHello = function() {
    console.log("Hello, my name is " + this.name);
  };
  return obj;
}

var person = createPerson("John", 25);
person.sayHello(); // 输出：Hello, my name is John
