What are the best practices for DOM optimization?
To optimize the DOM, you should minimize the number of elements, reduce reflows, and use efficient selectors.
Can you explain what reflows are?
Reflows occur when changes to the DOM require the browser to recalculate the layout, which can be performance-intensive.
How can I reduce reflows in my web application?
You can reduce reflows by batching DOM updates, using CSS for animations instead of JavaScript, and avoiding layout thrashing.
Are there any tools to help with DOM optimization?
Yes, tools like Chrome DevTools, Lighthouse, and various performance monitoring libraries can help analyze and optimize your DOM.
