Haskell is a statically typed, pure functional programming language known for its strong emphasis on immutability, type safety, and declarative programming. Developed in the late 1980s, Haskell is designed to allow developers to write highly reliable and maintainable code by using functional principles like first-class functions, lazy evaluation, and strong type inference.
Haskell’s powerful type system enables developers to catch errors at compile time, reducing the likelihood of bugs in production. Its support for lazy evaluation, where expressions are only computed when needed, allows for the creation of efficient, elegant code that handles infinite data structures and complex algorithms with ease.
Haskell is widely used in academia, research, and industries requiring high assurance, such as financial services and cryptography, due to its ability to handle complex abstractions and guarantee correctness through formal reasoning. The language’s growing ecosystem, including tools like the Glasgow Haskell Compiler (GHC) and the Cabal package manager, continues to support a diverse community of developers.
