Difficile
Que va afficher ce composant ?
const MyComponent = () => {
const [index, setIndex] = useState(1);
setIndex(2);
return <div>{index}</div>;
}

Don't understand why it will create an infinite loop

Because updating your state will create a new render. You should only update your state conditionnaly (for exemple using a "onClick" or a condition)
The loop will look like this :
- Rendering
- Updating state (with setIndex(2))
- Rendering
- Updating state (with setIndex(2))
etc...
