//-----2

//----1

//The abbreviation of prototype mode--2

//================================
/* {name:"Chinese",
age:20,}
The above format is itself an object. If you pay it to another object's prototype, it will make
All properties of another object. In essence, it is inheritance
*/
//================================
//Standard object inheritance examples, Person, Student
//Define a Person object
function Person(){};
="Chinese";
=20;
var person=new Person();
//Define a Student object
function Student(){};
=person;
="It can be available";
var stu=new Student();
="No love is allowed";
alert();//Instance inherited from the parent object
alert();//New attribute added by yourself
//Define a Teamleader object
function Teamleader(){};
=new Student();//Inherited from Student
=8;//Teamleader's own attributes
//Create your own instance
var teamleader=new Teamleader();
alert();
="Not available";
alert();
