Worked on enhancing the Stock Widget in the homarr-labs/homarr repository by implementing international number formatting and clear positive change signage for stock data. Focused on improving the locale-aware presentation of prices, absolute changes, and percentage changes, the solution ensures that positive changes are always displayed with a '+' prefix for better readability. Leveraged front end development skills using React and TypeScript, with careful attention to JavaScript language features for formatting logic. These enhancements addressed the need for accurate and user-friendly financial data display, supporting users in making informed decisions by presenting information consistently across different locales and regions.
