Noam Helfman developed and enhanced the Scroll Timing API within the MicrosoftEdge/MSEdgeExplainers repository, focusing on standardizing scroll performance measurement across platforms. Over two months, Noam defined the API surface, established metrics for responsiveness, smoothness, frame drops, and velocity, and clarified measurement criteria to improve accuracy. The work included comprehensive documentation and a demonstration polyfill, enabling developers to integrate and assess scroll performance more effectively. Using JavaScript and Markdown, Noam refined entry emission rules and provided detailed guidance for frame counting and smoothness, demonstrating depth in API design, front end development, and performance optimization without addressing bug fixes during this period.
