What is the difference between reflow and repaint in web development?
Reflow is the process of recalculating the positions and sizes of elements in the layout, while repaint is the process of redrawing elements on the screen without changing their layout.
Can you give me an example of when reflow occurs?
Reflow occurs when you change the size of the browser window, add or remove elements from the DOM, or change the CSS properties that affect layout.
What about repaint? When does that happen?
Repaint happens when you change the color or visibility of an element without affecting its layout, like changing the background color.
How can I minimize reflow and repaint for better performance?
You can minimize reflow and repaint by batching DOM changes, using CSS transitions, and avoiding layout thrashing.
