And to add on to the other commenter, there's also a `useLayoutEffect` hook which fires synchronously after a react render but before the browser paints the render.

Basically `useLayoutEffect` fires in the same phase as `componentDidUpdate`, but it's discouraged unless you really need that timing (to do things like read the DOM directly and/or trigger a re-render before paint)
