  The older I get, the more “it depends”.

    This. Nothing is a silver bullet.

      Not even silver bullets.

  Object-oriented design is about message-passing; messages are more important than objects. Classes are completely irrelevant – there’s an entire branch of object-oriented language design without classes!

    That’s not OOP anymore.

    I’d argue “message passing” is an implementation detail rather than part of OOP. And it’s an implementation detail that is rarely used in modern OOP languages.

      Whatever it may have become in later years, Alan Kay, who is often called “The Father of Object-oriented Programming”, outlined the message-passing idea as the main concept he was driving at, originally.

      He also says that he probably misnamed it.

      Here’s a discussion in which the man himself makes a (small) appearance: …stackexchange.com/…/so-what-did-alan-kay-really-…

      JavaScript is an example of how OOP can be done without classes (before they were added to appease Java enthusiasts).

  Also, I take issue with the claim that OOP is all about “objects”. It’s also about classes.

  Depending on the language, classes are just objects too. So its still just about objects.

  Just like walking doesn’t really compete, like at all, with flying in an aircraft, Functional and Object Oriented Programming are at their best when you use whichever approach makes sense for a given situation and in any reasonably complex software that means your code should be full of both.

  I’m not really sure sure that’s true.

  In FP languages like Haskell, you get tools like algebraic data types, typeclasses, and pattern matching.

  FP is really opposed to imperative programming, while objects are opposed to algebraic data types.

  You can write OO code that’s 100% fully functional, and you can write code in Haskell where you barely notice you never once used an object.
