Code Smells

Each category of code smell has its own pattern, root cause, and recommended remediation. Every developer writes smelly code at some point. Code smells typically originate from bad habits and deferred decisions. Code smells are symptoms of structural problems rather than functional bugs. The core problem with code smells is not that they appear but that they go unrecognized or unaddressed. Code smells make development unpleasant and can significantly slow velocity. A code smell is a characteristic in source code that possibly indicates a deeper underlying problem.
