Key differences between Java and Janet
| Characteristic | Java | Janet |
|---|---|---|
| Syntax | C-style, verbose, uses braces and semicolons, statically structured. | Lisp-like, uses s-expressions, minimal and concise. |
| Paradigm | Object-oriented, also supports imperative and some functional features. | Multi-paradigm: functional, imperative, and metaprogramming (macros). |
| Typing | Statically typed, strong type checking at compile time. | Dynamically typed, types checked at runtime. |
| Performance | High performance with JIT compilation, suitable for large-scale applications. | Interpreted, lightweight and fast for scripting, but generally slower than Java for heavy computation. |
| Libraries and frameworks | Extensive standard library, vast ecosystem of third-party libraries and frameworks. | Smaller standard library, fewer third-party libraries, but easy to interface with C. |
| Community and support | Large, mature community with extensive documentation and support. | Small but active community, limited resources and support compared to Java. |
| Learning curve | Moderate to steep, especially for beginners due to verbosity and strictness. | Gentle for those familiar with Lisp, but s-expression syntax may be unfamiliar to newcomers. |
