What are circular dependencies and how do they differ across programming languages?

What are circular dependencies and how do they differ across programming languages?

Circular dependencies occur when two or more modules depend on each other directly or indirectly. This can lead to issues like infinite loops or runtime errors.

Can you give examples of how different languages handle circular dependencies?

Sure! In Python, circular imports can be resolved using import statements inside functions. In Java, circular dependencies can lead to compilation errors, and it's often resolved by refactoring the code.

What are the best practices to avoid circular dependencies?

To avoid circular dependencies, you can use design patterns like Dependency Injection, keep modules focused on single responsibilities, and refactor code to reduce interdependencies.

Are there any tools to detect circular dependencies?

Yes, there are tools like ESLint for JavaScript, PyLint for Python, and various IDEs that can help detect circular dependencies in your code.
