Does this skill support older versions of Ruby?

While it focuses on Ruby 3.x features like Ractors and Data classes, it covers fundamental concepts such as blocks, procs, and error handling applicable to all modern Ruby versions.

What Ruby 3.x specific features are covered?

It includes detailed guidance on pattern matching, Data classes, Ractors for parallelism, endless methods, numbered block parameters, and refinements.

Can it help with Ruby on Rails development?

Yes. While it focuses on the core Ruby language, mastering these core features is essential for writing efficient, clean, and idiomatic code within the Rails framework.

How does it handle performance-related queries?

The skill provides patterns for using Lazy Enumerables to process large datasets efficiently and Ractors to achieve true parallel execution without GVL constraints.
