This example shows how functional inheritance can be used in javascript without #prototype or #new and take advantage of Javascript's ability with argument & objects
//define an object
var baseObject = function(publicName,privateVar){
var baseContext = { // object literal
Name:publicName,
getInfo : function(){
return this.Name + " you are " + privateVar ; //Any local variable remain private
}
};
return baseContext;
};
// inherit form baseObject
var person = function(name,occupation){
var that = baseObject(name,occupation); //inherit from base
that.action = function(){ //extend base with a method
return "You know nothing " + that.Name ;
}
return that;
};
//calls
debugger;
console.clear();
// create instance of the extended class
var man = person("John Snow","Stark");
var person1 = (man.getInfo());
var person1does= (man.action());
man.Name = "Eddard"; // Change the name of person
man.privateVar = "Lord of wintefell"; //will not change as it's private
var person2 = (man.getInfo());
var person2does = (man.action());
//print
console.log(person1);
console.log(person1does);
console.log(person2);
console.log(person2does);
