Factory creation in AngularJS

createFactory

var app = angular.module('capeloMod', []);

//factory style, more involved but more sophisticated
app.factory('demoFactory', function() {
   var publicValue = 0;
	var privateValue = 0;
	
	function apiFn() {
	    return this.publicValue++;
	}
	
	function apiFn2() {
	    return privateValue++;
	}
    
    return {
        apiFn : apiFn,
        apiFn2 : apiFn2,
        publicValue : publiValue
    };
});
