Sample

function Counter()
{
    let $count = 0;
    let $doubleCount := $count * 2;

    function increment()
    {
        $count = $count + 1;
        $count = $count + 1;
    }

    return (
        <button type="button" onClick={increment}>
            {$count} / {$doubleCount}
        </button>
        );
}
