Haskell vs Scala: Which is better for functional programming?

What are the main differences between Haskell and Scala?

Haskell is a purely functional programming language, while Scala is a hybrid that combines functional and object-oriented programming. Haskell emphasizes immutability and lazy evaluation, whereas Scala allows mutable data and has a more flexible type system.

Which one is easier to learn for a beginner?

Haskell can be challenging for beginners due to its strict functional paradigm and abstract concepts. Scala, being more versatile and similar to Java, might be easier for those with some programming background.

What are some practical applications of Haskell?

Haskell is often used in academia, data analysis, and for building robust systems. Companies like Facebook and Google have used Haskell for specific projects due to its strong type system and reliability.

Can you give examples of projects that use Scala?

Scala is widely used in big data processing frameworks like Apache Spark, as well as in web applications with frameworks like Play. Companies like Twitter and LinkedIn utilize Scala for its scalability and performance.
