Hi Guys, I have been a software developer for over 10 years. Using programming languages such as C#, Java & C++. However, I think the functional programming languages https://en.wikipedia.org/wiki/Functional_programming such as F#, Python & Scala are going to take over in a few years. Even C# is starting to look more and more like a functional language. I thought i'd post this to see if we Africans are following the trends n the industry. What are your thoughts if any? Regards T007OSH |

No they are not. Python, Scala and C# are not functional. They are OOP, and you can do some functional programming with them. F#, Haskell, Lisp, ML, Clojure, these are functionally. Of those, Haskell and Clojure seem to be thriving and the market share for them is very small. They will not take over, but smart individuals and companies will tap them to gain an edge. |

Python, F# and Scala are functional languages. However, they can be used in an Object Oriented programming context too. In the financial industry these languages are used more than Haskell which you mentioned. I agree though that smart people will start to use them to gain an edge. Also any new developer who doesn't want to be concerned+ constrained with a particular OS or platform I would advise should learn these (in my Opinion). You will also learn to write cleaner code this way  |

What is the difference between OOP and this functional programming? I know that c++ nigguhs switched to this type about 1Year ago. What's really cool about it when compared to object oriented programming? |

Java has also integrated functional programming technique with Lambdas and stream. So it's no longer only procedural, OOP and generic programming language. I want to believe functional programming is the future, because Java has enhanced most of their data structures so as to be compatible with functional programming. I must say functional programming is amazing and exciting, it simplifies programming a lot. |

DonSegmond: Scala is functional, as well as oop 1 Like |

Here are a few features of functional programming languages: - Referential transparency - Immutable data types - Higher order functions - Lazy evaluation - Strong type system Languages like Python, C# and Java support some of those but they are definitely not functional. Scala is both imperative and functional and so allow both paradigms. If you are looking for a truly functional programming language I'd strongly recommend Haskell. If you want something further than functional (eg dependently typed languages) checkout Idris, Agda or Coq. Idris and Agda are written in Haskell as is PureScript. 2 Likes |

It's worth adding that among the practical benefits of immutability, referential transparency, etc. is that it makes reasoning about concurrency a lot easier. This is especially important now that all machines are multicore, and applications must often be scaled to clusters of hundreds of nodes. 1 Like |

Pls keep on the analysis as am learning from it. Still a starter though! |

What's your stake on Arnold C? |
| Re: Functional Programming. The Future? by Borwe: 8:41am On Dec 27, 2015 |
What is Arnold C? Sounds like a language written by Arnold Schwarzenegger fun's |

omohayek: Well said, In addition outside of concurrency, it allows one to trust a function. Once you have a function that has been tested, you can be certain that it will behave exactly as designed since it doesn't keep state. State is the beast that brings forth exponential growth in complexity as the software grows. By being immutable, we have a clear separation of data and code which goes against everything OOP stands for. |

Hope you all had a wonderful Christmas. I found this on stack overflow http://stackoverflow.com/questions/2078978/functional-programming-vs-object-oriented-programming apologies if this isn't allowed. The selected answer almost likens the use of functional languages to civil engineering style of doing things which is tried, tested and works 99.9 percent of the time. I mean when last have you heard of a bridge collapsing? I'm not saying I totally agree with the analogy but if it gives software that level of trustworthiness I'm on board and will actively start using one or two of the functional languages for my personal projects at home. Some might argue though that it could stifle creativity which is really what we enjoy doing (well I do) |

foldl: I was going to post this but glad to see someone else beat me to it. What has been mentioned above are tools to help the main objective of functional programming. They are not what makes a language functional or not. The article was one of the best descriptions of this. Basically, your functions have clearly-defined inputs and doesn't change anything outside its own scope. This makes it easier to test each little bit of your program. Also makes it easier to write better programs because all the components used to create it do exactly what was advertised and nothing else. Every component is simple, predictable and testable. I don't contain myself completely to its rules but code that is clear to me is pretty functional, so I guess I'm approaching that day by day. |
