Raku is a member of the Perl family of programming languages. Formerly known as Perl 6, it was renamed in October 2019. Raku introduces elements of many modern and historical languages. Compatibility with Perl was not a goal, though a compatibility mode is part of the specification.
Raku offers many features such as:
- Object-oriented programming including generics, roles and multiple dispatch;
- Functional programming primitives, lazy and eager list evaluation, junctions, autothreading and
- hyperoperators (vector operators);
- Parallelism, concurrency, and asynchrony including multi-core support;
- Definable grammars for pattern matching and generalized string processing;
- Optional and gradual typing.
Raku is multi-paradigmatic. It supports procedural, object oriented, and functional programming.
