I am facing a problem when the app is running the timer is working correctly however when I reset the timer the countdown timer is stuck in the initial state.

    const [timer, setTimer] = useState(30)

 useEffect(() => { 
    let interval = setInterval(() => { 
      setTimer(prev => {
        if (prev === 1) clearInterval(interval)
        return prev - 1
      })
    }, 1000)
    newQuestion()
    return () => clearInterval(interval)

  

  }, [])

  const handleReset = () => { 
 setTimer(30)
    setScore(0) 

  }
