Duck typing in computer programming is an application of the duck test—"If it walks like a duck and it quacks like a duck, then it must be a duck"—to determine whether an object can be used for a particular purpose. With nominative typing, an object is of a given type if it is declared to be (or if a type's association with the object is inferred through mechanisms such as object inheritance). In duck typing, an object is of a given type if it has all methods and properties required by that type. Duck typing can be viewed as a usage-based structural equivalence between a given object and the requirements of a type. See structural typing for a further explanation of structural type equivalence. (Wikipedia).

RubyConf 2014 - Strong Duck Type Driven Development
By, John Cinnamond As a language, Ruby plays fast and loose with the type system. Developers rely on duck typing to check that the things they want to do with an object are permissible. Whilst this freedom makes writing code frictionless and often a whole lot of fun, it doesn't always sca
