OOP(Object Oriented Programming)

Object Oriented Programming is here,since I was born. You can try:
var p = new program();
for(var i=0;i<100;i++){
for(var j=0;j<100;j++){
p.child[0][0] = new program();
};
};

but it will be a long running script.

The thing is objects usually have properties and methods to access those properties.
