calling setState in useEffect does not change state

[left pagoda]

i'm having trouble setting an initial value to a useState variable in useEffect from localStorage, i use the associated setter and yet setDisplayA( value ) never changes the value of displayA, what am i doing wrong?

    const [displayA, setDisplayA] = useState(undefined)
    //on mount
    useEffect( () => {
        const value = window.localStorage.getItem("stateSwapVisibilityButton") === "true"
        setDisplayA( value )
        console.log("should be true, never is:", displayA === value)
    }, [])```
=> `should be true, never is: false`
i understand this is more of a react question than a next question but im too tired to go in the proper forums :P
