  1. The caveats section says that

    “`
    const DismissableContent = () => {
    const content = (dismiss) =>

    return (

    )
    }
    “`

    avoids extra re-renders compared to

    “`
    const DismissableContent = () => {
    return (
    } />
    )
    }
    “`

    but both variants still recreate the inline function on every re-render. What should work is one of the following:

    “`
    const content = (dismiss) =>
    const DismissableContent = () => {
    return (

    )
    }
    “`

    “`
    const DismissableContent = () => {
    const content = useCallback((dismiss) => , []);
    return (

    )
    }
    “`
