在JS数组中创建对象

var obj1 = { name: 'John', age: 25 };
var obj2 = { name: 'Jane', age: 30 };
var arr = [obj1, obj2];

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

var person1 = new Person('John', 25);
var person2 = new Person('Jane', 30);
var arr = [person1, person2];

var personProto = {
  greet: function() {
    console.log('Hello!');
  }
};

var person1 = Object.create(personProto);
person1.name = 'John';
person1.age = 25;

var person2 = Object.create(personProto);
person2.name = 'Jane';
person2.age = 30;

var arr = [person1, person2];
