Alec Song worked on the ucsb-cs156-f24/proj-happycows-f24-09 repository, focusing on refactoring the LeaderboardTable component to improve how totalWealth values are displayed. By applying direct USD formatting within the Cell component using JavaScript and React, Alec enhanced both readability and rendering consistency without altering the underlying data. This approach maintained functional parity while making the codebase more maintainable and adaptable for future formatting or localization needs. The work demonstrated a clear separation of concerns in frontend development, enabling easier future extensions to support additional currencies or locales, and contributed to a more stable and understandable UI.
