Language comparison
Key differences between Grain and Janet
| Characteristic | Grain | Janet |
|---|---|---|
| Syntax | Grain uses a syntax inspired by OCaml and ReasonML, featuring pattern matching, type inference, and functional constructs. | Janet has a Lisp-like syntax with s-expressions, parentheses, and a minimalistic, homoiconic structure. |
| Paradigm | Primarily functional, with support for immutable data and algebraic data types. | Multi-paradigm, supporting functional, imperative, and metaprogramming styles. |
| Typing | Statically typed with type inference and a strong type system. | Dynamically typed, with types checked at runtime. |
| Performance | Compiles to WebAssembly, offering good performance for web and some server-side applications. | Interpreted or compiled to bytecode for a custom VM, generally fast for a scripting language but not as fast as native or WebAssembly code. |
| Libraries and frameworks | Limited ecosystem, with a growing but small set of libraries focused on WebAssembly. | Includes a standard library and some community packages, but the ecosystem is relatively small. |
| Community and support | Small but active community, with official documentation and some community resources. | Small, niche community with active maintainers and a helpful Discord server. |
| Learning curve | Moderate, especially for those familiar with functional programming or OCaml-like languages. | Steep for those new to Lisp syntax, but simple core concepts make it approachable for experienced programmers. |
