How to update a React component's dependencies in useEffect without creating an infinite loop

Question

I have a React component where I need to wait for a stored value (member) to be updated and then delete a member based on a condition before setting the stored value. However, this obviously creates a loop.

useEffect(() => {
    if(members.length > 0) {
        setMembers(members.filter((item) => item.name != 'Bob'));
    }

}, [members]);

Is there any good way to solve this problem? Based on my application setup, I really need to do this in this component.

You can try using updater state const [update, setUpdate] = useState(false) and pass update as a dependent array. When the member list is updated, use setUpdate(!update).
