What are some best practices for manipulating the DOM in JavaScript?

Some best practices include minimizing direct DOM manipulation, using document fragments, and caching selectors.

Can you explain why minimizing direct DOM manipulation is important?

Minimizing direct DOM manipulation improves performance by reducing reflows and repaints, leading to smoother user experiences.

What are document fragments and how do they help?

Document fragments are lightweight containers that hold DOM elements. They allow you to build a DOM structure off-screen before adding it to the document, which is more efficient.

Any tips for caching selectors?

Yes! Store frequently accessed elements in variables to avoid querying the DOM multiple times, which can slow down performance.
