Who Wants to be a Ruby Engineer?
summary
A live Ruby quiz that runs real snippets and reports exact outputs and failures, not high-level platitudes: it shows real IRB-running snippets including use of :: to call instance methods, &&= logical-and assignment, proc vs lambda argument handling and array deconstruction, the flip‑flop operator and triple‑equals on lambdas, anonymous class name mutation, for-loop scoping, character code shoveling, and odd sleep return values; contestants use audience and AI lifelines and the demos reliably execute so viewers know what actually works.
