Key differences between COBOL and Raku
| Characteristic | COBOL | Raku |
|---|---|---|
| Syntax | English-like, verbose, designed for readability and business logic. | Flexible, expressive, supports multiple paradigms, concise and modern. |
| Paradigm | Procedural, with some support for object-oriented programming in later versions. | Multi-paradigm: procedural, object-oriented, functional, concurrent, and more. |
| Typing | Static typing with strong emphasis on data structure definitions. | Gradual typing; supports both dynamic and static typing. |
| Performance | Optimized for batch and transaction processing; high performance for business applications. | Generally slower than COBOL due to its flexibility and features; performance improving but not a primary focus. |
| Libraries and frameworks | Limited, mostly focused on business, finance, and legacy systems. | Growing ecosystem, CPAN6 for modules, but smaller than more established languages. |
| Community and support | Mature, but shrinking; strong in legacy enterprise environments. | Small but active and enthusiastic community; modern online resources. |
| Learning curve | Gentle for business logic, but can be tedious due to verbosity and legacy concepts. | Steep due to flexibility and breadth of features, but modern documentation helps. |
