Use constructors to define "range classes"

Usage 1:

Bytes --------------------------------------------------------------------------------------------------------------

<SCRIPT>

// This is a constructor used to initialize the newly created "range object"

// Note that no object is created and an object is returned, only Initialization

Statement 1:

Function a (x ){

This. f = X;

}

Statement 2:

VaR A = function (){};

// All range objects are inherited from this object

// Note that the attribute name must be prototype.

A. Prototype = {

Add: function (y ){

Return number (this. f) + number (y );

}

};

// New A () creates a range object

X = new A (10). Add (8 );

?

Console. Log (x); // output: 18

</SCRIPT>

?

Usage 2:

Bytes --------------------------------------------------------------------------------------------------------------

<SCRIPT>

VaR A = function (x) {This. x = x ;};

A. Prototype = {

Add: function (y ){

Return this. x = This. x + number (y );

}

};

?

A. Prototype. Includes = function (){

???? Return this. x * 2;

}

?

_ Q = new;

_ Q. x = 50;

Console. Log (_ q. Events des ());
