Language comparison
Key differences between Elm and Janet
| Characteristic | Elm | Janet |
|---|---|---|
| Syntax | Haskell-like, functional, statically typed, uses significant whitespace and clear type annotations. | Lisp-like, uses s-expressions, minimalistic and homoiconic, dynamic structure. |
| Paradigm | Purely functional, declarative, focused on immutability and side-effect-free code. | Multi-paradigm, primarily functional and imperative, supports metaprogramming. |
| Typing | Static, strong, inferred types with no runtime exceptions. | Dynamic, weak, types are checked at runtime. |
| Performance | Compiles to highly optimized JavaScript, good performance for web apps. | Interpreted or compiled to bytecode, fast for a scripting language, suitable for embedding. |
| Libraries and frameworks | Focused ecosystem, mainly for front-end web development, limited but high-quality libraries. | Smaller ecosystem, general-purpose scripting, fewer libraries but can interface with C. |
| Community and support | Active but niche community, good documentation, slower pace of updates. | Small and niche community, responsive core developers, limited resources. |
| Learning curve | Steep for those new to functional programming or static typing, but beginner-friendly error messages. | Moderate, easier for those familiar with Lisp, but s-expressions can be unfamiliar to newcomers. |
Common questions
