Even bad code can function. But if code isn’t clean, it can bring a development organization to its knees. Every year, countless hours and significant resources are lost because of poorly written code. But it doesn’t have to be that way.
Noted software expert Robert C. Martin presents a revolutionary paradigm with Clean Code: A Handbook of Agile Software Craftsmanship. Martin has teamed up with his colleagues from Object Mentor to distill their best agile practice of cleaning code “on the fly” into a book that will instill within you the values of a software craftsman and make you a better programmer—but only if you work at it.
What kind of work will you be doing? You’ll be reading code—lots of code. And you will be challenged to think about what’s right about that code, and what’s wrong with it. More importantly, you will be challenged to reassess your professional values and your commitment to your craft.
Clean Code is divided into three parts. The first describes the principles, patterns, and practices of writing clean code. The second part consists of several case studies of increasing complexity. Each case study is an exercise in cleaning up code—of transforming a code base that has some problems into one that is sound and efficient. The third part is the payoff: a single chapter containing a list of heuristics and “smells” gathered while creating the case studies. The result is a knowledge base that describes the way we think when we write, read, and clean code.
Readers will come away from this book understanding
How to tell the difference between good and bad code
How to write good code and how to transform bad code into good code
How to create good names, good functions, good objects, and good classes
How to format code for maximum readability
How to implement complete error handling without obscuring code logic
How to unit test and practice test-driven development
This book is a must for any developer, software engineer, project manager, team lead, or systems analyst with an interest in producing better code.
Every software developer needs to keep refreshing their skills.
And this book provides some really good ideas on improving the useful life of the code you write.
Some of the suggestions it makes you have probably heard before, either from other books or other experienced developer. But this book goes further, providing a set of well reasoned guidelines, from the simple to grasp (e.g. why comments are bad, consistency of code style, why checking for null is bad!) to the quite complex steps required to refactor your code again and again (and again) to achieve "clean code".
Read it at least twice. Then again.
