ArthurJCQ developed a foundational object-oriented Person class for the ArthurJCQ/MIAGE-INF1-2024-2025 repository, focusing on robust domain modeling in JavaScript. Leveraging JavaScript classes, prototypes, and object-oriented programming principles, he implemented properties for age, first name, last name, and city, along with methods to increment age, manage city data, and check majority status. The class also included static members to support class-level utilities, providing a reusable and consistent API for future modules. This work established a clear, maintainable structure for representing user data, laying groundwork for downstream integration and improving codebase consistency without introducing unnecessary complexity.
