What are the best practices for code modularity?

Code modularity refers to the practice of breaking down code into smaller, manageable, and reusable components. Best practices include using clear naming conventions, keeping modules focused on a single responsibility, and ensuring modules are loosely coupled.

Can you explain why loose coupling is important?

Loose coupling allows modules to be developed, tested, and maintained independently. This reduces dependencies and makes it easier to update or replace parts of the code without affecting the entire system.

What tools can help with maintaining code modularity?

Tools like linters, code formatters, and modular design frameworks can help maintain code modularity. Additionally, using version control systems like Git can assist in managing changes across modules.

How do I structure my project for better modularity?

Start by organizing your project into directories based on functionality. Each module should have its own directory, and you should define clear interfaces for interaction between modules.

Any tips for refactoring existing code to improve modularity?

Identify large functions or classes and break them down into smaller, reusable components. Ensure each component has a single responsibility and refactor iteratively to avoid introducing bugs.
