javascript arraylist

Question

Can we attach arraylist or function with a javascript object at runtime

function abc(){
        this.a = 1;
        this.b = 2;
    }
    var obj = new abc();
    obj.list.add("abc"); // list is not declare in class  abc

@Arslan Ahson I think you should read a little and then come here to ask questions that are explained even in Wikipedia! — Bakudan

I think you need to write

obj.push("abc")

you will first have to declare the list, then you could access/modify it as any other object prop :

 var obj = new abc();
 obj.list = [];//or obj.list = new Array();
 obj.list.add("abc");
