Use when working with Ruby — the dynamic, object-oriented language and its runtime (MRI/CRuby). Covers the object model, metaprogramming, core types, blocks/procs/lambdas, control flow and exceptions, I/O and encoding, the concurrency model (Threads, Fibers, Ractors, GVL), garbage collection and ObjectSpace, the RubyGems/Bundler package system, the interpreter CLI and tooling (irb, erb, rake, rdoc/ri), environment variables, and the standard library.

Comprehensive reference for the Ruby programming language and its reference implementation (MRI/CRuby) — covering the object model, metaprogramming, core types, control flow, I/O and encoding, concurrency, garbage collection, the RubyGems/Bundler package system, the interpreter CLI and tooling, environment variables, and the standard library.
Source file (.rb)
→ Ripper (parse to AST)
→ YARV compiler (compile AST to bytecode instructions)
→ YARV VM (per-instruction dispatch)
→ runtime services (ObjectSpace, GC, Thread scheduler, load path)
→ I/O, exit
