In plain words

Roll.js is a lightweight JavaScript library designed to track element position and scroll behavior on web pages.

The library offers a straightforward approach to position and scroll tracking without unnecessary complexity, making it useful for creating responsive page interactions and animations that depend on scroll position data.
