Infinite loop useEffect() hook

So, I am using hook useState():

const [dailyData, setDailyData] = useState({});

And useEffect() hook to fetch data from API:

 useEffect(() => {
    const fetchAPI = async () => {
        setDailyData(await fetchDailyData())
    }

    console.log(dailyData)

    fetchAPI();
});

But the problem is that these requests are endless.

I'm new in React, so it would be great if you'd explain why this is caused.
