The Howdy Glossary

Raku is a programming language developed by Larry Wall to address the need for advanced data structures, improved parallelism, and enhanced object-oriented programming. Designed as a general-purpose language that merges elements from multiple programming languages including Perl, Ada, C#, Haskell, Python, and Ruby, Raku aims to balance expressiveness and efficiency. It features custom syntax constructs through grammars, gradual typing for flexibility between static and dynamic typing, lazy evaluation for optimized performance by executing calculations only when results are requested, and access to external libraries via the Foreign Function Interface (FFI).

Raku stands out with its unique offerings like customizable syntax through grammars which allow developers to create new syntax without altering the core grammar structure. The type system supports gradual typing enabling both specified and inferred types based on requirements. Lazy evaluation is implemented for performing calculations only when needed thus improving performance optimization. Further enhancing its extensibility is Raku's ability to natively access libraries written in other languages through FFI which increases its interoperability.

In a competitive landscape featuring languages like Python with its readability and extensive libraries; Ruby known for elegant syntax commonly used in web development; Perl with strong text processing capabilities; and Haskell offering functional programming paradigms — Raku differentiates itself significantly. Its support for grammars allows unparalleled flexibility in creating custom syntax while gradual typing caters to varying needs of specification or inference of types. Its implementation of lazy evaluation boosts performance optimization particularly in demand-based scenarios whereas native access via FFI strengthens integration potential across different language ecosystems positioning Raku as an expressive yet efficient choice among modern programming options.
