What is duck typing?


What does duck typing mean in software development?


Solution

  • It is a term used in dynamic languages that do not have strong typing.

    The idea is that you don't need to specify a type in order to invoke an existing method on an object - if a method is defined on it, you can invoke it.

    The name comes from the phrase "If it looks like a duck and quacks like a duck, it's a duck".

    Wikipedia has much more information.
