Haskell is a purely Functional Programming language, known for its strong static typing and elegant approach to computation. It embraces Lazy Evaluation, allowing developers to build robust and concise software. Developed in the late 1980s, it is named after logician Haskell Curry.
A key feature of Haskell is its advanced Type System, which includes powerful Type Inference. This helps catch errors at compile time, contributing to program reliability. Haskell manages Side Effects and I/O using Monads, allowing for referential transparency while still interacting with the outside world. It is widely used in academia for research and teaching, and in industry for applications requiring high assurance and concurrency.
