Logic Practice

const buttons = document.querySelectorAll('button');

buttons[0].addEventListener('click', () => {
    number = prompt('pick any number');
    if (number < 11) {
        alert('You’ve won a civit');
    } else if ((number >= 11) && (number < 21))
    {
        alert('You’ve won a civit');
    } else
    {
        alert('you get nothing');
    }
});
