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 software design as an exercise in human
relationships
