Let's first look at the invocation
;});Parenizor.method (' toString ', function () { Return ' (' + this.getvalue () + ') ';});
This syntax may be of little use, but it is easy to see the form of the class. Method methods accept a method name and a function and place them in a class as a public method.
Now we can write
Myparenizor = new Parenizor (0);myString = Myparenizor.tostring ();
As expected, mystring is "(0)".
Now we're going to build another class that inherits from Parenizor, and it's basically the same except the To

Class inheritance is familiar to most developers. As long as they have classes with methods, they can be instantiated as objects.

Because "directly inheriting prototype" has the preceding disadvantages, there is a fourth method that uses an empty object as an intermediary.
Var F = function (){};
F. prototype = Animal. prototype;
Cat. prototype = new F ();
Cat. prototype. constructor = Cat;
F is a null object, so it hardly occupies memory. In this case, modifying the prototype object of Cat will not affect the prototype object of Animal.
