Language comparison
Key differences between Bash and Janet
| Characteristic | Bash | Janet |
|---|---|---|
| Syntax | Shell scripting syntax, command-oriented, uses lots of special characters and minimal structure. | Lisp-like syntax with parentheses, prefix notation, and code-as-data philosophy. |
| Paradigm | Imperative, procedural, focused on command execution and scripting. | Multi-paradigm (functional, imperative, metaprogramming), supports macros and higher-order functions. |
| Typing | Dynamically typed, weak typing, everything is treated as a string. | Dynamically typed, stronger type system than Bash, supports multiple data types (arrays, tables, etc.). |
| Performance | Slower, especially for complex logic, as it often spawns external processes. | Faster, compiled to bytecode, suitable for embedding and more computational tasks. |
| Libraries and frameworks | Limited standard library, relies heavily on external Unix commands and utilities. | Rich standard library, growing ecosystem of modules, can interface with C libraries. |
| Community and support | Large, mature community with extensive documentation and resources. | Smaller, newer community, but active development and growing documentation. |
| Learning curve | Gentle for basic scripting, but can become steep due to quirks and inconsistencies. | Steeper for those unfamiliar with Lisp syntax, but more consistent and powerful once learned. |
