Globalne promenljive se kače na window objekat. Mali test:

var global_variable = 12;
      
var some_function = function() {
    global_from_function = 13;
    var local = 14;
    
    console.log(window.global_variable);
    console.log(window.global_from_function);
    console.log(window.local);
}();

Vraća:

> 12
> 13
> undefined

Edit: LOL! Koliko odgovora
