var prom1 = 'prom1 proměnná v kontextu objektu window';
prom2 = 'prom2 globální proměnná';
alert(prom1);
alert(prom2);
//window - "nejvyšší" objekt prohlížeče
alert(typeof window.prom1);
alert(typeof window.prom2);
//this - objekt, ve kterém zrovna jsme, tedy window
alert(typeof this.prom1);//lokální proměnná objektu window není vlastností window
alert(typeof this.prom2);//"globální" proměnná je vlastností window
