Key differences between Gleam and Grain

CharacteristicGleamGrain
SyntaxStatically typed, ML-inspired syntax with clear, concise structure; similar to Elm or ReasonML.Statically typed, functional syntax inspired by OCaml and ReasonML, designed for clarity and simplicity.
ParadigmFunctional programming, immutable data, strong emphasis on pattern matching and algebraic data types.Functional-first, supports algebraic data types, pattern matching, and immutability.
TypingStatic, strong, and inferred typing with a focus on type safety.Static, strong, and inferred typing with a focus on soundness and safety.
PerformanceCompiles to Erlang BEAM bytecode, inherits Erlang's concurrency and reliability, suitable for scalable backend systems.Compiles to WebAssembly (Wasm), optimized for fast startup and execution in browser and server environments.
Libraries and frameworksGrowing ecosystem, can use Erlang and Elixir libraries via interop, but native Gleam libraries are still limited.Smaller ecosystem, focused on core language features, limited libraries, but can interoperate with JavaScript in Wasm.
Community and supportActive, friendly, and growing community with good documentation and responsive maintainers.Smaller, enthusiastic community, early in development, with improving documentation and support.
Learning curveGentle for those familiar with functional programming; approachable syntax and good error messages.Moderate, especially for those with functional programming background; some learning curve due to Wasm concepts.
