Language comparison
Key differences between Janet and Elm
| Characteristic | Janet | Elm |
|---|---|---|
| Syntax | Lisp-like, uses s-expressions and parentheses, minimalistic and concise. | Haskell-inspired, uses indentation and algebraic data types, more traditional functional syntax. |
| Paradigm | Multi-paradigm (functional, imperative, metaprogramming with macros). | Purely functional, strongly emphasizes immutability and functional programming. |
| Typing | Dynamically typed. | Statically typed with strong type inference. |
| Performance | Interpreted, fast for a scripting language, suitable for scripting and embedding. | Compiles to highly optimized JavaScript, good performance for web applications. |
| Libraries and frameworks | Smaller ecosystem, fewer libraries, but can use C libraries via FFI. | Focused ecosystem for web development, good set of core libraries, but limited compared to JavaScript. |
| Community and support | Small but active community, limited resources and support. | Larger and more established community, more learning resources and active forums. |
| Learning curve | Gentle for those familiar with Lisp, may be unusual for others. | Steep for beginners due to functional purity and static typing, but excellent error messages help. |
Common questions
