The setState furnction from useState should be in the dependency array when called from within useEffect

As talked about here and explained in this article. The setState function from the useState hook should be in the dependency array when it is called from useEffect. This is not done in the documentation. The clearest example is probably from the hooks-faq where this example is given:

It doesn't have to be. The second value from useState, the setter, is stable. It never changes and thus is redundant to put in the dependency array. See the Note in this section: https://reactjs.org/docs/hooks-reference.html#usestate
