Haskell stands out as a standardized, general-purpose functional programming language characterized by strong static typing and non-strict semantics. Named after logician Haskell Curry, the language advocates that "a function is a first-class citizen." With functional programming at its core, Haskell governs programming structures emphasizing functions as the primary control construct.

Interest in lazy functional languages surged following Research Software Ltd's release of Miranda in 1985, resulting in over a dozen non-strict purely functional languages by 1987. Notably, Miranda was widely employed but remained proprietary. A milestone in functional programming history occurred during the conference on Functional Programming Languages and Computer Architecture held in Portland, Oregon when participants decided to form a committee to define an open standard for these languages. The committee's objective was to amalgamate these functional languages into a common framework for future research in functional-language design.

Haskell's prominent features encompass lazy evaluation, pattern matching, list comprehension, type classes, and type polymorphism. As a purely functional language, Haskell prioritizes functions without side effects. Specific constructs represent side effects distinctly from typical functions – facilitating model representations akin to other languages' impure functions by introducing side-effects where necessary. Haskell boasts a robust static type system founded on Hindley–Milner type inference with notable contributions like type classes that enable principled overloading and serve various purposes.

The construction representing side effects is exemplary of a monad – offering a universal structure to model diverse computation types including error handling, nondeterminism, parsing, and software transactional memory. Although monads are defined as regular data types, Haskell simplifies their usage with useful syntactic sugar.

Haskell maintains an open published specification with multiple implementations available. A vibrant community surrounds the language aiding in the existence of over 5400 third-party open-source libraries and tools accessible via the online package repository Hackage.

The primary Haskell implementation – GHC – functions as both an interpreter and native-code compiler compatible with most platforms. Noteworthy for its high-performance concurrency and parallelism features along with an enriched type system encompassing contemporary concepts like generalized algebraic data types and type families – GHC serves as a formidable embodiment of Haskell's potential.
