Key differences between Haskell and Grain

CharacteristicHaskellGrain
SyntaxUses a concise, indentation-sensitive syntax with significant whitespace and mathematical notation.Has a clean, modern syntax inspired by ML-family languages, designed to be approachable and readable.
ParadigmPurely functional programming with strong emphasis on immutability and functions as first-class citizens.Functional-first, but allows some imperative constructs; designed for WebAssembly with a focus on functional programming.
TypingStatically typed with strong, inferred types and advanced type system features like type classes and higher-kinded types.Statically typed with type inference, but with a simpler type system compared to Haskell.
PerformanceCompiled to native code, generally good performance but can be unpredictable due to lazy evaluation.Compiles to WebAssembly, optimized for fast startup and execution in web environments.
Libraries and frameworksRich ecosystem with many libraries and frameworks for various domains, especially backend and academic use.Smaller and newer ecosystem, focused on WebAssembly and web-related libraries.
Community and supportLarge, established community with extensive documentation, tutorials, and active forums.Small but growing community, limited resources and support compared to Haskell.
Learning curveSteep learning curve due to advanced concepts and unique syntax.Gentler learning curve, designed to be accessible to newcomers, especially those interested in WebAssembly.
