What is the difference between useEffect with an empty dependency array [] and useEffect with no dependency array at all?

Accepted Answer

The difference between useEffect with an empty dependency array [] and no dependency array is crucial. The empty array runs the effect only once after the initial mount, while no array runs the effect after every render.
