" summary

Covers the Ruby features Rails developers actually use: using rails console (IRB plus Rails) to inspect strings, arrays, hashes and their methods; mutating vs nonmutating methods like reverse! vs reverse; array.shuffle and map with blocks; symbols vs string keys and old/new hash syntax; defining classes, inheriting from String, and reopening core classes; Rails adding helpers like 1.megabyte and 10.days.ago; controller methods return nil in plain Ruby but render views under Rails.
