On https://reactjs.org/docs/... it is declared that useEffect runs after render is done.

However... if you put into useEffect an expensive calculation or operation e.g. "add +1 to x billion times", it will get stuck after updating the data, but before the re-render is done.

This leads to inconsistency between the DOM and the state which I believe is a foundational point of react. Moreover, the statement that "useEffect runs after render" is false.

The solution is to add a timeout to that expensive operation, e.g. 50 ms so the re-render can finish itself.

The integrity of my belief in react has received a shrapnel today. Argh :D Guys, how this can be? It seems that useEffect is not being run after re-render.
