Clean Code - Uncle Bob / Lesson 1

Caption notes

Robert C. Martin uses code that adds setup and teardown steps to a test page to explain why he values the maintainer’s reading experience. He likens refactoring to writing a news story: let the reader see what the code does first, with details available when needed. He also gives his own test for whether a function does one thing. If he can still extract another meaningful function, he keeps splitting the code and uses names to explain what the parts do.
