Worked on the Leaflet/Leaflet repository to enhance the clarity of the GeoJSON API documentation, specifically focusing on the onEachFeature callback in L.geoJSON. The update explicitly described that the callback receives both the feature and the corresponding layer as arguments, addressing a common source of confusion for developers. This documentation improvement was implemented through a single, traceable commit, supporting easier code reviews and future updates. The work demonstrated skills in JavaScript and technical documentation, with attention to API documentation standards and version control practices. No major bugs were fixed during this period, with efforts concentrated on improving developer onboarding and maintainability.
