Haskell is a functional programming language known for its strong type system and emphasis on purity and immutability. Here are some common use cases for Haskell:

Academia and Research: Haskell is widely used in academic and research settings due to its strong theoretical foundations and expressive type system. It serves as a practical language for exploring and implementing new programming language concepts and functional programming techniques.

Financial and Quantitative Applications: Haskell's strong type system and purity make it suitable for financial and quantitative applications where correctness and reliability are critical. It enables precise modeling of financial calculations and reduces the risk of errors in complex algorithms.

Compiler Development: Haskell is often used for developing compilers, interpreters, and domain-specific languages (DSLs). Its powerful type system and pattern matching capabilities make it well-suited for building language processing tools and code generators.

Web Development: Haskell has a growing ecosystem of web development frameworks and libraries. It offers strong type safety and advanced abstractions for building scalable and high-performance web applications. Frameworks like Yesod and Servant provide elegant solutions for building web APIs and web applications.

Concurrent and Parallel Programming: Haskell's pure and immutable nature, combined with its lightweight concurrency model, makes it a suitable choice for concurrent and parallel programming. It offers built-in features like Software Transactional Memory (STM) and lightweight threads, enabling developers to write concurrent programs with ease.
