Ah see my mistake now.

There are so many articles about OO JavaScript programming and sometimes can be everything mix up :-)

Yes. I know that MyLibrary is OO. That's why I look out there :-) But not everything is clear for me. For example the inherit function I tried to understand how this method works and adapt to my example. It did not work me. So I wanted to do something new, step by step to understand the exact object oriented JavaScript.

Yes. Agree.
