I'm following the React course and I'm stuck on the useEffect lesson. The infinite re-render concept is confusing me.

📚 Great question! useEffect infinite re-renders are a common learning hurdle. Let me break this down step by step to make it crystal clear!

Here's the code from the lesson that's causing the issue:

useEffect(() => {
setData(fetchData());
}, []);

🎯 Perfect! I can see the issue. This is a classic mistake students make. The problem is calling fetchData() directly. Here's the correct way:

useEffect(() => {
setData(fetchData());
}, []);
useEffect(() => {
const loadData = async () => {
const result = await fetchData();
setData(result);
};
loadData();
}, []);
