Question : javascript nested classes

I am trying to achieve this OOP style (1 main class with internal classes) but I am getting error "MiniAds is not defined"

<script>
new MiniAds.Widget({
width: 200,
height: 100
}).render();
</script>

MiniAds = window.MiniAds || {};

MiniAds.Widget = function (x) {
    this.init(x);
};
    
MiniAds.Widget.prototype = function () {           
    return {
        init : function () {
            alert(1);
            return this;            
        }
        render : function () {
            alert(2);
            return this;            
        }
    };
}

var MiniAds = window.MiniAds || {};

MiniAds.Widget = function (x) {
	return this; 
};

MiniAds.Widget.prototype = {
        init : function (p) {
            alert(p);    
        },
        render : function (p) {
            alert(p);           
        }
    };

var w = new MiniAds.Widget('hello');

w.init('foo');
w.render('bar');
