Worked on improving the MoonBit documentation by addressing deprecated string handling methods in the moonbitlang/moonbit-docs repository. Focused on code refactoring and documentation, the update replaced instances of .char_at(index) with .get_char(index).unwrap() in the MoonBit tour example, ensuring safer string access and reducing compiler warnings. This change promoted reliable handling of string operations by explicitly unwrapping the Result, aligning with best practices in MoonBit. The targeted commit enhanced documentation quality and aimed to streamline contributor onboarding. The work demonstrated attention to detail in both code safety and clarity, utilizing MoonBit and emphasizing robust documentation and maintainability practices.
