Language comparison
Key differences between Janet and Carbon
| Characteristic | Janet | Carbon |
|---|---|---|
| Syntax | Lisp-like, uses s-expressions and parentheses, minimalistic and homoiconic. | C++-like, uses curly braces and familiar C-style syntax, designed for readability and familiarity for C++ developers. |
| Paradigm | Multi-paradigm: functional, imperative, and metaprogramming via macros. | Multi-paradigm: primarily object-oriented and procedural, with support for generic programming. |
| Typing | Dynamically typed. | Statically typed. |
| Performance | Interpreted, generally slower than compiled languages, but suitable for scripting and embedding. | Designed for high performance, aims to match or exceed C++ performance, compiled. |
| Libraries and frameworks | Smaller ecosystem, core standard library with some third-party modules. | Very early stage, limited libraries, but aims for interoperability with C++ ecosystem. |
| Community and support | Small but active community, niche usage, limited resources. | Backed by Google, growing interest, but still experimental and not widely adopted. |
| Learning curve | Steep for those unfamiliar with Lisp syntax, but simple core concepts. | Easier for C++ developers, but new concepts and still evolving. |
