In a new post to his site Jason McCreary makes a case for writing clean code in your development processes. He makes three main suggestions of practices you can integrate into your workflow to help make the code you write cleaner.
I noticed [legacy codebases] all suffer from the same fundamental issue - inconsistency. Often the result of years of code patching, large teams, changing hands, or all of the above.
This creates a problem because we read code far more than we write code. So as I read a new codebase these inconsistencies distract me from the true code. My focus shifts to the mundane of indentation and variable tracking instead of the important business logic.
In my experience, I find I boy scout a new codebase in the same way. Three simple practices to improve the readability of the code.
His three suggestions for improving the overall code quality center around standardized formatting rules, consistent naming practices and avoiding nested code. He uses an example piece of code to help illustrate these recommendations with explanations for each.
