编程: 创建对象的方式(字面量或构造函数)

1、通过对象直接量创建的对象,都具有同一个原型对象,并可以通过Object.prototype获得对原型对象的引用,即创建的对象继承自Object.prototype

实例

<script>
let obj = {'color':'cyan','size':36,'type':'sport'};
document.write(obj);
</script>

2、通过关键字new和构造函数调用创建的对象的原型就是构造函数(Object()、Array()、Date()、RegExg())的prototype属性的值

实例

<script>
let point = new Object({x:10,y:20});
document.write(point);
let person = new Object();
person.name = 'yaoming';
person.height = 216;
person.sports = function(){
    return 'play basketball';
}
document.write(person);
document.write(person.sports());
document.write(person.name);
document.write(person['height']);
</script>
