Yes, as functional programming can be done in any language, you can use it as a web developeron a day to day basis.
Should you? it depends upon the problem you are solving. Functional programming is a programming paradigm and where you should use it depends upon the problem you are solving.
To make the decision simpler, think whether it is easier to solve some problem by using OOPs concepts, where encapsulation, polymorphism, inheritance like features can make your life easier?
If yes, do not go for functional programming there and simply use OOPs.
If your application is going to perform complex computation / calculation / business logic and involving heavily concurrent processing, Functional programming can offer lots of tools and advantages in such cases.
These are just different styles of building the structure and elements of programs, so it’s all about using right tool for the right job.rest anything can be done using anything.
Functional programming in web development:
JavaScript supports functional programming and it is very much supportive when we are in context of web development.React framework is heavily influenced by functional programming principles and used in many web applications out there.
Also, you can find many web applications built and running with frameworks developed on functional programming languages listed below:
• WebSharper (F#)
• Snap (Haskell)
• Lift (Scala)
• Ocsigen (OCaml)
• Chicago Boss, Zotonic (erLang)
Hope So my answer will help anyone.
