**Project Summary** `arrive.js` is a lightweight, dependency‑free JavaScript library that monitors the DOM for elements added or removed using Mutation Observers. It lets developers easily create and clean up event listeners for newly inserted nodes or departing elements, with options for once‑only callbacks, attribute monitoring, timeouts, and Promise‑based syntax. **Target Audience** It’s ideal for front‑end engineers—especially those using vanilla JS or jQuery—who need robust, performant detection of dynamic DOM changes (e.g., for single‑page apps, widgets, or content‑loading features) without pulling in heavy frameworks. The library works in all modern browsers and can be integrated via npm or a simple script tag.
