During May 2025, Sanchit focused on improving the stability of the Music Blockly module within the code-dot-org/code-dot-org repository. He addressed a bug related to block selection by refactoring the selection logic, replacing the previous select and unselect methods with a safer addSelect and removeSelect approach. This change prevented unintended recursive calls, reducing the risk of stack overflows and enhancing reliability for end users. Sanchit’s work centered on front end development using JavaScript and TypeScript, leveraging his expertise in Blockly to align the module’s interaction patterns with broader platform stability and maintainability goals. No new features were introduced.
