Summary

abstraction is a core idea in code. It means you hide_details and expose_essentials. It separates interface from implementation. Key benefits are reduced_complexity, better reuse, and improved maintainability. Common forms include functions, modules, classes, abstract_class, and interface. Types include data_abstraction for state and control_abstraction for behavior. Use clear contracts and stable method_signatures to define expectations. Clients depend on the interface, not the details.
