What I learned

    event.preventDefault();

    const inputValue = document.querySelector('input').value;
    let checkEmail = inputValue.match(/\b[A-Za-z0-9._+%-]+@[A-Za-z]+\.[A-Za-z]{2,}\b/);

    if(!checkEmail){   
        errorMsg.classList.add('is_visible');
        errorMsg.parentElement.nextElementSibling.classList.add('input-error');
    }
    else
        window.location.href = `${window.location.origin}/subscribe.html?${inputValue}`; 
})
