Browser event loops distinguish tasks from microtasks and coordinate rendering opportunities, while Node.js organizes host callbacks into event-loop phases with additional queue behavior. The language and each host runtime therefore contribute different parts of the result.</p> <p><figure> <img src="https://www.compilemymind.com/posts/javascript-event-loop-tasks-microtasks-rendering/concept-flow.svg" alt="JavaScript event loop task and microtask reasoning flow" width="1200" height="830" loading="lazy" decoding="async"> </figure></p>
