How can I refactor my code for better maintainability?

Refactoring for maintainability involves restructuring your code without changing its external behavior. Start by identifying complex or duplicated code.

What are some common techniques for refactoring?

Common techniques include extracting methods, renaming variables for clarity, and reducing code duplication.

How do I know when my code needs refactoring?

Look for code smells like long methods, large classes, or repeated code. If it's hard to understand or modify, it likely needs refactoring.

Can you give me an example of a code smell?

Sure! A common code smell is a method that does too much, often referred to as a 'God Method'. It should be broken down into smaller, more focused methods.
