Classes in ExtendScript ( Object Orientation)

Is it possible to work with "true" Object Orientation in ExtendScript? I've tried to create classes and Objects with JS Synthax, but that won't work:

class Person {
    constructor(name, surname) {
        this.name = name;
        this.surname = surname;
    }
}

var person = new Person('Jack', 'Smith');
alert(person);

This only returns "invalid use of reserved word class".

What I am actually trying to do in the long run is to build an UI based on Objects. So, speaking in Pseudocode:

Class myUI {
constructor(group , dropdown1, text1  )
this.group = group (parameter)

this.dropdown1 = group.add(dropdownlist (parameter))

this.text1 = group.add(edittext (parameter))

}

...etc


myUI(group,dropdown,text);

Any Idea how something like this could work?

ExtendScript is based on super old ECMA version 3.something. So to imitate a Class, you'd need to use the old way, like this:

function Person(name, surname){
	this.name = name;
	this.surname = surname;
}

var person = new Person('Jack', 'Smith');
alert(person);

Thanks Tomas, that seems to work great!

First test running fine:

var myPanel = new Window("palette","title",undefined);

var dropContent = ["Slideshow","Texttafel","Typo Big","Video Container"];

function myUI(group, dropdownlist,myFirstText){
	this.group = group;
	this.dropdownlist = dropdownlist;
     this.myFirstText = myFirstText;
}

var newRow = new myUI('group', 'dropdownlist,undefined,dropContent','edittext {text:\'bla\'}');

myPanel.add(newRow.myFirstText);

myPanel.center();
myPanel.show();

Hello, is there any chance you could send me some sort of post about classes in after effects? I heard from a coder that they are useful but I just don't really know what they are. Google seems to think I am looking for extendscript courses when I type"class" so it's hard to find anything about it. I wanna learn! xD thanks!
