A strange object in a window object

Question

I can’t understand why it windowis under selfand selfunder the object window.

if you go to dev-tools or Firebug and write window, you get the object DOM windowthat selfis under this object. The strange part is that windowit is under again self!

You can write

window.self.window.self.window.self.window.self.window.self.window.self.window.self.window.self.window.self.window.self.window.self.window.self.window.self.window.self.window.self.window.self.window.self.window.self.window.self.window.self.window.self.window.self.window.self.window.self.window.self.window.self.window.self.window.self.window.self.window.self.window.self.window.self.window.self.window.self.window.self.window.self.window.self.window.self.window.self.window.self.window.self.window.self.window.self.window.self.window.self.window.self.window.self.window.self.window.self.window.self.window.self.window.self.window.self.window.self

and you will get the object window!

How?!
