Key differences between COBOL and Janet
| Characteristic | COBOL | Janet |
|---|---|---|
| Syntax | English-like, verbose, designed for readability and business logic. | Concise, Lisp-like with s-expressions, designed for scripting and embedding. |
| Paradigm | Procedural, imperative, with some support for structured programming. | Multi-paradigm: functional, imperative, and metaprogramming (macros). |
| Typing | Static typing with explicit data declarations. | Dynamically typed. |
| Performance | High performance for batch and transaction processing on mainframes. | Good performance for scripting and embedding, but not optimized for heavy computation. |
| Libraries and frameworks | Limited modern libraries; mostly legacy business and financial libraries. | Growing but small standard library; some third-party modules, especially for scripting and embedding. |
| Community and support | Large legacy community, strong enterprise and vendor support, but aging. | Small, active open-source community, mostly hobbyists and enthusiasts. |
| Learning curve | Steep for modern developers due to outdated paradigms and verbosity. | Moderate, especially for those familiar with Lisp-like languages; concise syntax can be unfamiliar. |
