Well, that's basics of javascript.
May you have variable `a`:
var a;
variable `a` can save any data, even function:
a = function(){};
a functions is something like callable object:
a(); // this is call of function
console.log(a.prototype); // this is property of the function object
you can create your own properties for the function:
a.myproperty = 'aloha';
console.log(a.myproperty);
a(); // function still works
there is special class Function (real type of the function)
var a = new Function(); // almost the same like:
var a = function(){};
the if you implement new properties into the Function, this properties
creates for all functions in the javascript code
so mootools creates property `periodical` for you, and saves there
function that helps you to call `getInterval` on a parent function:
var a = function();
a.periodical(1000);
something like that.. better to you to read good javascript books ;)
