Language comparison
Key differences between Janet and R
| Characteristic | Janet | R |
|---|---|---|
| Syntax | Lisp-like, uses s-expressions with minimal syntax, parentheses-based. | C-like, uses standard mathematical notation, more verbose and traditional. |
| Paradigm | Multi-paradigm: functional, imperative, and metaprogramming. | Primarily functional and vectorized, with some object-oriented features. |
| Typing | Dynamically typed. | Dynamically typed. |
| Performance | High performance, suitable for scripting and embedding, compiles to bytecode. | Moderate performance, optimized for statistical computing but slower for general tasks. |
| Libraries and frameworks | Limited but growing ecosystem, focused on general scripting and embedding. | Extensive libraries for statistics, data analysis, and visualization. |
| Community and support | Small but active community, less mainstream support. | Large, well-established community with extensive documentation and support. |
| Learning curve | Steep for those unfamiliar with Lisp syntax; easier for those with Lisp experience. | Moderate, especially for users with a statistics or data science background. |
Common questions
Frequently Asked Questions
How do I convert Janet to R?
