This free online converter lets you convert code from Gleam to Grain in a click of a button. To use this converter, take the following steps -
| Characteristic | Gleam | Grain |
|---|---|---|
| Syntax | Statically 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. |
| Paradigm | Functional programming, immutable data, strong emphasis on pattern matching and algebraic data types. | Functional-first, supports algebraic data types, pattern matching, and immutability. |
| Typing | Static, strong, and inferred typing with a focus on type safety. | Static, strong, and inferred typing with a focus on soundness and safety. |
| Performance | Compiles 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 frameworks | Growing 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 support | Active, friendly, and growing community with good documentation and responsive maintainers. | Smaller, enthusiastic community, early in development, with improving documentation and support. |
| Learning curve | Gentle 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. |
