In pseudo-classical pattern, the object is created by a constructor function and it’s methods are put into the prototype.

Pseudo-classical pattern is used is frameworks, for example in Google Closure Library. Native JavaScript objects also follow this pattern.

All methods and properties of the object can be added in the constructor. This method doesn’t use prototype at all.

This pattern is special, because it doesn’t use "new".
The object is created by a simple function call, similar to Python-style:

var animal = Animal("fox")
var rabbit = Rabbit("rab")
