Developed a foundational object-oriented model for the ArthurJCQ/MIAGE-INF1-2024-2025 repository by implementing a reusable JavaScript Person class. This class encapsulated properties such as age, first name, last name, and city, and provided methods to increment age, manage city data, and determine majority status. The approach leveraged JavaScript classes, prototypes, and static members to demonstrate both instance-level and class-level logic, ensuring consistency in user representation across modules. The work included a complete API surface with constructor, getters, and setters, laying the groundwork for future integration and domain modeling within the project’s broader JavaScript codebase.
