Can you explain what reflows and repaints are in web development?
Sure! Reflows and repaints are processes that the browser uses to update the layout and appearance of a webpage.
What triggers a reflow?
A reflow is triggered by changes to the DOM, such as adding or removing elements, or changing styles that affect layout.
And what about repaints? How are they different?
Repaints occur when changes are made that affect visibility but not layout, like changing the background color.
How can I minimize reflows and repaints for better performance?
You can minimize them by batching DOM changes, using CSS for animations, and avoiding layout thrashing.
