Language comparison
Key differences between Janet and COBOL
| Characteristic | Janet | COBOL |
|---|---|---|
| Syntax | Minimalist, Lisp-like with s-expressions, concise and modern. | Verbose, English-like, designed for readability and business logic. |
| Paradigm | Multi-paradigm: functional, imperative, and metaprogramming. | Procedural, with some object-oriented features in later versions. |
| Typing | Dynamically typed. | Statically typed. |
| Performance | Efficient for scripting and embedding, but not optimized for heavy computation. | Optimized for batch processing and large-scale business data handling. |
| Libraries and frameworks | Limited but growing ecosystem, focused on scripting and embedding. | Limited modern libraries, mostly legacy business and financial systems. |
| Community and support | Small, active, and modern open-source community. | Large legacy user base, strong support in enterprise and government sectors. |
| Learning curve | Moderate for those familiar with Lisp-like languages; concise syntax. | Steep for modern programmers due to verbosity and legacy concepts. |
Common questions
Frequently Asked Questions
How do I convert Janet to COBOL?

What are the main differences between Janet and COBOL?
Janet and COBOL differ in syntax, type system, standard libraries, and common idioms, so copying code line for line usually will not compile. The converter maps each Janet construct to its closest COBOL equivalent. See the comparison table below for the key differences between Janet and COBOL.
Is the converted COBOL code accurate?
The AI produces high-quality COBOL code that preserves the behavior of your original Janet code and follows COBOL conventions. It handles common patterns, data structures, and idioms for both Janet and COBOL. For large or performance-critical code, review and test the COBOL output before using it in production.
Can I convert an entire Janet project to COBOL?
You can convert Janet files one at a time by pasting each file's code. For a full migration, convert each file and then review how classes, dependencies, and project structure map from Janet to COBOL. Signing in for free raises the input limit to 25,000 characters per conversion for larger files.
