I am a Scala beginner and coming from Object Oriented Paradigm. While understanding Functional programming part of Scala, I was directed to Haskell - the pure Functional programming language.
Exploring SO question-answers, I found that Java - Haskell has interoperability.
I am curious to know that similarly does Scala-Haskell interoperability exist or not?
Can a function library written in Haskell be used in Scala application?
As per answer given by Don Stewart: It is possible.
Integration of Haskell Function Library in Scala application will be straight and easy or will require complicated tweaks?
With integrated Haskell Function Library, the Scala application will run on JVM or will require different arrangement?

Haskell is concise, safe and faster to use, whereas Scala is also concise, fast and safer with many libraries support. Haskell has first-class functions and pure, whereas Scala is strict and impure to use in terms of functional programming features.
Both are great languages, but if you're a beginner, I would recommend Haskell. Scala is a very hard language to learn and use properly, because it allows you to choose between imperative and functional programming and even mix the two. If you're inexperienced, this tends to create messy code.
Clojure vs Scala: SummaryClojure is a Lisp dialect; it's a dynamically typed, compiled, functional JVM language. It is known for being robust, practical, but a bit slow in collection manipulation. Scala is a statically typed, object-oriented, functional JVM language. It is known for being fast, clean, and organized.
Frege is a Haskell for the JVM. Like any Haskell, it is purely functional, enjoys a strong static type system with global type inference and non-strict - also known as lazy - evaluation. Frege compiles to Java, runs on the JVM, and uses any Java library you want.
I found that Java - Haskell has interoperability. I am curious to know that similarly does Scala-Haskell interoperability exist or not?
Well given that interoperability is transitive, and given that (hj_interop : Haskell <-> Java) and (js_interop : Java <-> Scala), we therefore conclude that Haskell <-> Scala.
If you want Haskell -> Scala, then just take Haskell -> Java from hj_interop, and Java -> Scala from js_interop. If you want Scala -> Haskell, then just take Scala -> Java from js_interop, and Java -> Haskell from hj_interop.
This isn't a very hand-holdy explanation of how to accomplish Haskell - Scala interoperability, but given existing interoperatilities, you just compose them in the obvious way. Scala does not provide any direct, convenient interoperability with Haskell that I am aware of, other than providing scalaz to add an extra Haskell-y feel to Scala.
