Avoid duplicating state with React hooks

React Tip: If you’re using useEffect just to update a state when another state changes — pause for a second. That’s often a signal you might be duplicating state unnecessarily. Example: useEffect(() => { setFiltered(users.filter(u => u.active)) }, [users]) Instead, derive it directly in render: const filtered = users.filter(u => u.active) Derived data > duplicated data. It keeps your component cleaner, more predictable, and easier to debug.

Totally agree, removing unnecessary state has saved me from so many weird edge case bugs, especially with async stuff.
