Refactoring from Good to Great

on YouTube ↗47m

" summary

Lots of live coding that keeps the specs green while refactorings happen: extracting temp vars into query methods, moving date logic from collection into an Order#placed_between and a new DateRange (then switching to Range.cover for a tiny perf win), replacing nil checks with a NullObject contact (deleting about ten lines), and isolating payment logic into a PaymentGateway adapter so gateway swaps and tests are easy. Uses quick vim macros, RSpec runs, small incremental steps and recommends books like Clean Code and Working Effectively with Legacy Code.
