Answer 1

function abc(){
 this.a = 1;
 this.b = 2;
}
var obj = new abc();
obj.list = ["abc"];

Answer 2

var obj = new abc();
obj.list = [];
obj.list.unshift("abc");

Answer 3

function abc(){
 this.a = 1;
 this.b = 2;
 }
 var obj = new abc();
 obj.list = new Array();
 obj.list.push("abc");

Answer 4

I think you need to write

obj.push("abc")

Answer 5

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");
