Language comparison
Key differences between Gleam and Janet
| Characteristic | Gleam | Janet |
|---|---|---|
| Syntax | Has a syntax similar to ML-family languages (like OCaml or Elm), with a focus on clarity and simplicity. | Uses a Lisp-like syntax with s-expressions, parentheses, and prefix notation. |
| Paradigm | Primarily functional, with strong emphasis on immutability and pure functions. | Multi-paradigm, supporting functional, imperative, and metaprogramming styles. |
| Typing | Statically typed with strong, inferred types and a focus on type safety. | Dynamically typed, with types checked at runtime. |
| Performance | Compiles to Erlang BEAM bytecode or JavaScript; performance is similar to other BEAM languages, optimized for concurrency. | Interpreted or compiled to bytecode for its own VM; generally fast for a scripting language, suitable for embedding. |
| Libraries and frameworks | Relatively young ecosystem, but can use Erlang and Elixir libraries via interop. | Smaller standard library, but includes batteries for scripting and embedding; fewer third-party libraries. |
| Community and support | Growing but still small community, with active development and good documentation. | Niche but enthusiastic community, mostly centered around scripting and embedding use cases. |
| Learning curve | Moderate, especially for those new to functional programming or static typing. | Steep for those unfamiliar with Lisp syntax, but simple core concepts for scripting. |
