Worked on improving localization reliability for Ukrainian users in the HeyPuter/puter repository by addressing issues in the ua.js translation file. Focused on correcting string literals and syntax errors that previously caused UI string problems, ensuring a smoother user experience for Ukrainian speakers. Utilized JavaScript and JSON string handling techniques, applying internationalization and localization best practices to enhance translation accuracy and maintainability. The work involved careful code review and precise commit management, resulting in reduced localization-related UI risks and a cleaner baseline for future i18n development. No new features were added, but a key bug fix improved overall translation quality.
