JavaScript Learning: Basic inheritance Mechanisms (2)

Inheritance function Person_mfgetname ()
{
return this.m_strname;
}

var myperson=new person ();
Myperson.getname ();

You can use any output statement to view the results. Of course this is only the first step!
Here is a key step: Inherit!

function Student ()//Extends Class:person
{
EXTENDS://My habit, but remember that you can't use lowercase letters. Because extends is a reserved word in JavaScript.
This. Super=person; The definition points to its parent class builder. The super here can't be in lowercase.
This. Super (); Call its parent class builder. This allows you to inherit all of the properties and methods from the parent class

Private
This.m_nstudentid=0;
}

Although the GetName () method is not seen in student, it can be invoked. Because he has inherited the person's GetName () method.

var mystudent=new Student ();
Mystudent.getname (); Note that the GetName method of its "parent class" is invoked, resulting in the return of "Guest".


This is true for JavaScript inheritance implementations. Just remember two steps:
　　
1: In "subclass" first defines a function pointing to "parent class" (any name can be, I am accustomed to using super)
2: Then call this function
　　
This allows you to inherit all the properties and methods of the parent class!
　　
What I suspect now is that since extends and super are reserved words, why does JavaScript not support inheritance?
I wonder if there is any better way? I hope you will advise ...
