I am wondering if someone knows where i can find the documentation of the scroll method? I am trying to understand [person13.com](http://person13.com) tutorial on creating  
components and the code is not documented properly at all.

[http://www.person13.com/articles/components/creatingcomponents.html](http://www.person13.com/articles/components/creatingcomponents.html)

This is where i am lost.

setInterval(this.\_parent,“scroll”,10);

if i understand clearly, the first parameter is the object, the second the function name and the third parameter is the parameter for the function.

but the function defined doesnt take any parameter like that. The articles another format of function calling  
setInterval(this.\_parent,“nudge”,10, 1);

and the defined nudge function takes only one parameter and which is 1.  
I dont understand where is the 10 going??? :hair:
