Anju Karanji contributed to the freeCodeCamp/freeCodeCamp repository by delivering a curriculum enhancement focused on the React children prop. Over the course of one month, Anju updated the curriculum to include clear explanations and practical examples, helping learners understand component composition and prop handling in React. The work involved front end development using JavaScript and Markdown, with changes implemented through a targeted curriculum update and a conventional commit process. Co-authored with Huyen Nguyen, this feature aligned the curriculum with modern React best practices. The contribution addressed a specific educational gap, providing depth and clarity for learners exploring React component hierarchies.
