Language comparison
Key differences between Groovy and Raku
| Characteristic | Groovy | Raku |
|---|---|---|
| Syntax | Similar to Java, concise, supports both static and dynamic syntax, easy for Java developers. | Distinct from Perl but Perl-inspired, flexible, supports multiple paradigms, more expressive and complex. |
| Paradigm | Object-oriented, supports functional and scripting paradigms. | Multi-paradigm: object-oriented, functional, concurrent, and declarative. |
| Typing | Dynamically typed by default, supports optional static typing. | Dynamically typed with gradual typing and strong type system. |
| Performance | Runs on JVM, generally slower than Java but faster than many scripting languages. | Slower than many mainstream languages, performance is improving but still a concern. |
| Libraries and frameworks | Rich ecosystem, access to Java libraries, popular frameworks like Grails. | Smaller ecosystem, growing set of modules, not as extensive as Groovy/Java. |
| Community and support | Large, active community, strong enterprise support, good documentation. | Smaller, passionate community, less commercial support, active development. |
| Learning curve | Easy for Java developers, gentle learning curve. | Steeper learning curve due to unique features and syntax. |
