What is the best refactoring technique to eliminate redundancy in calculations across Screen Actions?

Creating a reusable Server Action or function for the calculation is the most effective refactoring technique to eliminate redundancy in calculations across Screen Actions. This approach promotes code reusability and maintainability. By centralizing the calculation logic in a Server Action, you ensure that any updates or changes to the calculation only need to be made in one place. This not only helps prevent bugs that can arise from having multiple copies of the same logic but also simplifies the overall application architecture.

When using a reusable Server Action, you encapsulate the logic, making it easier to test and manage. Additionally, it enhances collaboration among team members since they can utilize this shared component in various parts of the application without duplicating their efforts. This method aligns with best practices in software design, where reducing duplication and enhancing modularity are key goals toward creating effective and efficient applications.
