Language comparison
Key differences between C# and Janet
| Characteristic | C# | Janet |
|---|---|---|
| Syntax | C-style, statically typed, uses braces and semicolons, verbose and familiar to Java/C++ developers. | Lisp-like, uses s-expressions and parentheses, concise and homoiconic, minimal syntax. |
| Paradigm | Multi-paradigm: object-oriented, functional, imperative, and component-oriented. | Multi-paradigm: functional, imperative, and metaprogramming; not object-oriented. |
| Typing | Statically typed with strong type checking at compile time. | Dynamically typed with type checking at runtime. |
| Performance | High performance, compiled to intermediate language (IL) and JIT-compiled by .NET runtime. | Interpreted or compiled to bytecode for a VM; generally fast for a scripting language but slower than C#. |
| Libraries and frameworks | Extensive standard library and rich ecosystem of frameworks (e.g., .NET, ASP.NET, Unity). | Minimal standard library, smaller ecosystem, but supports embedding and FFI for C libraries. |
| Community and support | Large, active community with strong corporate backing (Microsoft), extensive documentation and support. | Small, niche community, limited resources and documentation, mostly open-source contributors. |
| Learning curve | Moderate to steep, especially for beginners; familiarity with C-style languages helps. | Steep for those unfamiliar with Lisp syntax; easier for those with Lisp experience, but minimalistic design can be approachable. |
