What is it?
Haskell is a purely functional programming language that emphasizes functions, immutability, and expressiveness. Unlike imperative languages where you write code that describes in detail how to do something, in Haskell you define what something is. It uses a strong static type system and lazy evaluation which means computations are not performed until necessary, leading to efficient execution and reduced runtime errors.
What are the key use cases?

Data Analysis

Haskell is used for data analysis where its high-level abstraction and expressiveness allow for clear and concise data manipulation. Its strong type system ensures data integrity throughout the analysis process.

Web Development

Despite not being as popular as some other languages for web development, Haskell boasts several frameworks such as Yesod and Snap that leverage its strong typing and purity for building reliable, secure web applications.

Financial Systems

Financial institutions value Haskell for its ability to enforce a high degree of accuracy and reliability in complex financial systems. The language’s features help in minimizing runtime errors and ensuring the correctness of the code.

Why would somebody want to learn it?
Learning Haskell can significantly improve a programmer's ability in abstract thinking and problem-solving within the realm of software development. It opens up opportunities in industries where code reliability and correctness are paramount, such as financial services, software security, and academia. Furthermore, understanding Haskell enhances a developer's skills in other programming paradigms, as it broadens their perspective on writing efficient, concise, and error-free code.
Who uses it?

Software Developers

Software developers who specialize in Haskell take advantage of its functional programming paradigm to write concise and robust code. They often work in domains requiring high reliability like finance and academia.

Data Scientists

Data scientists might use Haskell for its strong capabilities in data handling and its support for concurrent programming, making it suitable for complex data analysis and modeling tasks.

Academics and Researchers

Academics and researchers use Haskell for theoretical computer science projects and to teach functional programming concepts. Its mathematical rigor and emphasis on purity make it ideal for educational purposes and exploratory programming.
