Why is functional programming not more popular?
I would say that one of the reasons that functional programming is not more prevalent is the lack of knowledge base. My experience is that corporations are very risk averse in terms of implementing technologies that are not main stream and would rather invest in tried and true frameworks (java, c++, c#).
Is functional programming still useful?
Because of its nature, functional programming is great for in-demand tasks such as data analysis and machine learning. This doesn’t mean that you should say goodbye to object-oriented programming and go completely functional instead.
Why is functional programming not more prevalent in software development?
I would say that one of the reasons that functional programming is not more prevalent is the lack of knowledge base. My experience is that corporations are very risk averse in terms of implementing technologies that are not main stream and would rather invest in tried and true frameworks (java, c++, c#).
What is the most popular functional programming language right now?
F# is one of the most popular functional programming languages. More popular than Haskell, Erlang, and and pretty much every other FP language except Scheme and Lisp. I assume the main reason being that you can just “sneak” it into existing .NET projects (it’s fully compatible with C#, VB .NET and the other CLR languages).
Is functional programming starting to catch on?
Functional programming is definitely starting to catch on – slowly but surely. For example, the startup I am building is using a functional language (Clojure) as the primary development language for the following reasons:
What are the advantages of using pure functions in programming?
Reliability – pure functions are much easier to reason about and test than stateful objects. Hence you can write better tests and validate the correctness of your code much more easily. Concurrency – functional languages emphasise immutability, which has enormous benefits for concurrent applications than need to run effectively on multiple cores.
