Worked on the momentum-design/momentum-ui repository to address a critical stability issue in the ComboBox component, focusing on front-end development with TypeScript and web components. The work involved resolving a type error that occurred when ComboBox options were provided as objects rather than strings. By explicitly casting option values and IDs to strings within the getOptionValue and getOptionId methods, the update ensured consistent handling of diverse option types and prevented runtime errors. Comprehensive test updates were included to cover object-option scenarios, reinforcing reliability and reducing the risk of regressions, ultimately improving the user experience and stability of the UI component.
