If a functional component receives data from the server in useEffect(), will it be a pure function?

Question

Functional programming

If a functional component receives data from the server in useEffect(), will it be considered a pure function? And why?

Answer 1

with the same input data (props or data received via api, for example), the rendering will not differ? will not. this means that fc will be considered a pure function, therefore it can be memoized (here it is worth mentioning that if the state is redefined in the component, then react will not pay attention to the memo wrapper and will still re-render)

Answer 2

No, it will not. A functional component will only be a pure function if it renders props and does nothing else.
