[Design Patterns in Javascript] Duck Typing in Javascript

Duck typing isn't exactly a design pattern, but I stumbled over it while working through the Strategy Design Pattern in Javascript episode, and I decided it made sense to include it here.

Duck typing is essentially a method that takes advantage of being able to substitute one object for another in a dynamic language if it has the same API.

If it walks like a duck and quacks like a duck, it must be a duck... or something like that.
