`rails c` with meturbocharge your use of the interactive console
summary
Console uses IRB with Bundler or full Rails boot to give access to gems and app context; Ripper’s SX shows the actual AST a method produces; reline provides multi line editing and history; use Benchmark.measure to time suspect ActiveRecord calls, run to_sql and explain to inspect queries and planner nodes, and spin up production with the sandbox mode flag to test heavy-data behavior while rolling back changes.
