Key differences between F# and Janet
| Characteristic | F# | Janet |
|---|---|---|
| Syntax | OCaml-inspired, indentation-sensitive, uses significant whitespace, concise and expressive. | Lisp-like, uses s-expressions (parentheses), minimal and homoiconic. |
| Paradigm | Multi-paradigm: functional-first, also supports object-oriented and imperative programming. | Multi-paradigm: functional and imperative, with strong emphasis on metaprogramming. |
| Typing | Statically typed with type inference. | Dynamically typed. |
| Performance | High performance, compiles to .NET bytecode, benefits from .NET JIT optimizations. | Interpreted or compiled to bytecode for its VM, generally fast for a scripting language but not as fast as statically compiled languages. |
| Libraries and frameworks | Access to .NET ecosystem, many libraries and frameworks available. | Smaller ecosystem, has a standard library and some community packages, but fewer options than F#. |
| Community and support | Active community, backed by Microsoft, good documentation and support. | Small but enthusiastic community, less mainstream support, documentation is growing. |
| Learning curve | Moderate; easier for those familiar with functional programming or .NET, but can be challenging for beginners. | Steep for those unfamiliar with Lisp syntax, but simple core concepts and small language size. |
