How we moved from focusing on state (what an object is) towards behavior (what an object does) while building our Purchase Options APIs as a way to create a more maintainable codebase.
Overview
The article discusses the importance of focusing on behavior rather than state in software development to create a more maintainable codebase. It highlights the challenges faced while implementing new features at Shopify and presents solutions that emphasize encapsulation and abstraction to prevent code complexity.

Key Actionable Insights
1Refactor existing code to prioritize behavior over state by creating wrapper classes that encapsulate logic.This approach helps in managing complexity and allows for easier modifications in the future, as changes to the internal logic won't affect other parts of the codebase.
2Implement a translation layer to facilitate reporting needs without exposing internal data structures.This ensures that data teams can access meaningful insights without being affected by changes in the codebase, thus maintaining the integrity of both the application and the reporting systems.
3Use encapsulation to limit the exposure of internal logic in your code.By ensuring that components only interact with necessary methods, you can reduce dependencies and improve the overall maintainability of your code.
