During the month, contributed a feature enhancement to the TanStack/virtual repository by introducing a new useScrollendEvent option, aimed at improving scroll end detection for long lists. This addition allows developers to opt into a debounced fallback mechanism for isScrolling, addressing inconsistencies in native scrollend support across browsers. The work focused on compatibility and developer ergonomics, providing finer control over scroll event handling. Implemented using JavaScript and TypeScript, the solution leverages API design and front-end development skills to enhance cross-browser reliability. No separate bug fixes were reported, as the primary effort centered on this targeted feature improvement and integration.
