What are code smells and how can I identify them?

Code smells are indicators of potential issues in your code that may affect its readability, maintainability, or performance. Common examples include long methods, duplicated code, and excessive parameters.

Can you give me some examples of specific code smells?

Sure! Some common code smells include:

1. Long Method: A method that is too long and does too much.
2. Duplicated Code: The same code appears in multiple places.
3. Large Class: A class that has too many responsibilities.

How can I fix these code smells?

To fix code smells, you can refactor your code. For example, break long methods into smaller ones, eliminate duplicate code by creating reusable functions, and apply the Single Responsibility Principle to your classes.

Are there tools that can help me identify code smells?

Yes, there are several tools available, such as SonarQube, ESLint, and PMD, which can help you analyze your code and identify potential code smells.
