How can minimizing DOM manipulation improve JavaScript performance?

Batching DOM updates and using document fragments reduces the number of changes applied to the live DOM, which lowers layout recalculations and improves rendering speed.

Minimizing DOM manipulations avoids excessive reflows and repaints, leading to smoother performance. Caching DOM references prevents repeated queries, while virtual DOM libraries optimize updates by batching and diffing changes efficiently. Additionally, separating read and write operations and using requestAnimationFrame for animations helps avoid layout thrashing and maintains responsiveness.
