GHC
GHC (Glasgow Haskell Compiler) is the primary and most widely used compiler for the Haskell programming language, translating Haskell source code into executable machine code. It provides a robust implementation of the Haskell 2010 language standard with numerous extensions, along with an interactive environment (GHCi) for development and debugging. As a key tool in the Haskell ecosystem, it includes optimizations, profiling tools, and support for concurrent and parallel programming.
Developers should use GHC when working on Haskell projects that require high performance, reliability, or advanced language features, such as in academic research, financial systems, or data-intensive applications. It is essential for building production-ready Haskell software due to its mature code generation, extensive library support via Cabal and Stack, and cross-platform compatibility on Linux, macOS, and Windows.
