Contributed to the freeCodeCamp/freeCodeCamp repository by enhancing the JavaScript debugging curriculum, specifically refining the RangeError example in the debugging lecture. Focused on clarifying how invalid array length assignments trigger RangeError, the update improved the accuracy and clarity of educational content. Applied JavaScript expertise and technical writing skills to ensure the example aligned with actual runtime behavior, making the material more accessible for learners and reducing confusion during debugging exercises. Collaborated closely with the curriculum team, following disciplined code review processes and thorough documentation practices, resulting in a targeted curriculum improvement that supports both student comprehension and instructional efficiency.
