The lesson explains useState() as :

useState() is a JavaScript function defined in the React library.

If it is defined in the React library, and we’re already importing import React from 'react', why do we have to import { setState() } separately from the same library?

This lesson says that stateSetter() updates the current value of this state. And by doing so it re-renders the function which is defining the component. Wouldn’t it result in an infinite loop, since we are calling the stateSetter() from inside the function?
