Key differences between Grain and Haskell

CharacteristicGrainHaskell
SyntaxC-like, inspired by JavaScript and Elm, concise and approachable for web developersUnique, heavily influenced by mathematical notation, uses significant whitespace and custom operators
ParadigmFunctional, with some imperative features; designed for WebAssemblyPurely functional, lazy evaluation, strong emphasis on immutability and mathematical functions
TypingStatic, strong, type inference, inspired by ML-family languagesStatic, strong, advanced type system with type inference, type classes, and higher-kinded types
PerformanceOptimized for WebAssembly, good performance in browser and web contextsCompiled to native code, good performance for CPU-bound tasks, but can be slower for some workloads due to laziness
Libraries and frameworksLimited ecosystem, focused on web and WebAssembly, fewer libraries availableMature ecosystem, many libraries and frameworks for various domains (web, concurrency, data science, etc.)
Community and supportSmall, growing community, limited resources and supportLarge, established community, extensive documentation, active forums and user groups
Learning curveGentle, approachable for those familiar with JavaScript or ElmSteep, especially for newcomers to functional programming and advanced type systems
