OLOO is quite different from both inheritance and composition. It embraces delegation rather than covering it up or running away from it. :)

Can you give an actual example of the difference between composition and delegation? In my definition those two are just two different perspectives on the same thing.

A super quick, simple illustration of the difference, which comes down to the fact that delegation is differential, whereas composition is complete:

For a bit more "real world" of a scenario, you can also compare the `LoginController` / `AuthController` mechanism here, first shown with inheritance+composition, and then shown with simpler OLOO-style delegation:

Ah, thanks. That clarifies things. Neat!
