Language comparison
Key differences between Erlang and Janet
| Characteristic | Erlang | Janet |
|---|---|---|
| Syntax | Prolog-inspired, uses pattern matching, functional style, and significant use of commas and periods. | Lisp-like, uses s-expressions, minimal and homoiconic, with a focus on simplicity. |
| Paradigm | Functional, concurrent, actor model, immutable data. | Multi-paradigm (functional, imperative, metaprogramming), supports coroutines. |
| Typing | Dynamically typed. | Dynamically typed. |
| Performance | Optimized for massive concurrency and distributed systems, not focused on raw computation speed. | Lightweight and fast for scripting and embedding, suitable for small to medium tasks. |
| Libraries and frameworks | Rich ecosystem for telecom, distributed, and concurrent systems (e.g., OTP). | Smaller standard library, growing ecosystem, focused on scripting and embedding. |
| Community and support | Mature, established community, strong support in telecom and backend industries. | Small but active community, mostly hobbyists and embedded systems developers. |
| Learning curve | Steep, due to unique syntax, concurrency model, and functional paradigm. | Moderate, especially for those familiar with Lisp-like languages; simpler core concepts. |
Common questions
Frequently Asked Questions
How do I convert Erlang to Janet?
