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 it
Explore the difference between changes to a system's behavior and changes to
its structure
Improve your programming experience by sometimes tidying first and sometimes
tidying after
Learn how to make large changes in small, safe steps
Approach design as a human activity with diverging incentives
