    // Gives you the width & height of <MyOtherComponent />
    console.log(width, height);

    // `boolean` which tells you if the width is _below_ the isMobile threshold.
    console.log(isMobile);

    // `boolean` which tells you if the width is _above_ the isWide threshold.
    console.log(isWide);

    return (
        <div>
