Worked on curriculum quality enhancements for the freeCodeCamp/freeCodeCamp repository, focusing on improving the accuracy of regex-related instructional content. Addressed a specific issue in the Regex Character Class Description by clarifying that the character class includes uppercase letters, which helps reduce confusion for learners and aligns with curriculum objectives. Utilized technical writing and curriculum development skills, leveraging Markdown to update documentation and ensure clarity. The fix was implemented with attention to code integrity and traceability, following standard commit practices. This targeted update supports more effective self-guided learning and contributes to consistent learner progress in regex exercises within the curriculum.
