Summary

Description

Messy code is a nuisance. "Tidying" code, to make it more readable, requires breaking it up into manageable sections. In this practical guide, author Kent Beck, creator of Extreme Programming and pioneer of software patterns, suggests when and where you might apply tidyings to improve your code while keeping the overall structure of the system in mind.Instead of trying to master tidying all at once, this book lets you try out a few examples that make sense for your problem. If you have a big function containing many lines of code, you'll learn how to logically divide it into smaller chunks. Along the way, you'll learn the theory behind software design: coupling, cohesion, discounted cash flows, and optionality.This book helps you:Understand the basic theory of how software design works and the forces that act on itExplore the difference between changes to a system's behavior and changes to its structureImprove your programming experience by sometimes tidying first and sometimes tidying afterLearn how to make large changes in small, safe stepsApproach design as a human activity with diverging incentives
