React - How to force a function component to render?

Question

I have a function component, and I want to force it to re-render.

How can I do so?
Since there\'s no instance this, I cannot call this.forceU

The accepted answer is good. Just to make it easier to understand.

Example component:

export default function MyComponent(props) {

    const [updateView, setUpdateView] = useState(0);

    return (
        <>
            {updateView}
        
    );
}

To force re-rendering call the code below:

setUpdateView((updateView) => ++updateView);
