The Shape of a Program
summary
Argues that complexity is usefully measured by the area under the indentation and demonstrates concrete refactorings that reduce it: invert nested ifs into guard clauses and pull blocks (like a big switch) out via extract function. Shows a nested example where these steps shrink indentation dramatically — more than half in the demo — turning a deep, hard-to-follow function into a short, flat one that compiles and keeps original behavior.
