In November 2024, Kenza Belkadhi developed an interactive UI feature for the ArthurJCQ/MIAGE-INF1-2024-2025 repository, introducing two selectable squares whose background colors change randomly, controlled by a toggle button. This feature enhanced user engagement by providing a responsive, client-facing element and required careful state management to ensure smooth toggling and animation control. Kenza implemented the solution using JavaScript and HTML, focusing on clear code organization and maintainability. While the work addressed a single feature, it demonstrated a solid grasp of front end development principles and laid a foundation for future UI extensions, with no major bugs reported during the period.
