During February 2025, Xiangwall focused on enhancing the CSE Machine for the Source Academy platform, working across the source-academy/frontend and source-academy/js-slang repositories. He clarified the BRANCH instruction documentation in TypeScript, improving the accuracy and maintainability of the frontend’s internal codebase. In the js-slang interpreter, he addressed for-loop and block execution issues by refactoring single-statement block handling and correcting for-loop initialization assignments. This work required skills in bug fixing, code refactoring, and compiler design, resulting in more robust and reliable interpreter behavior. His contributions demonstrated a thoughtful approach to both documentation and core interpreter development within the project.
