Working with a sign up form that can have conditional inputs. It is possible that the Country value is not always necessary when signing up. Is there a "conditional IF statement" through which I could do the form check? In otherwords, check signupForm.country.length only if Country is true. For context, below is the code where I am trying to implement the logic:

    const submit_button_disabled =
        !(agreeTerms
        && signupForm.email.length > 0
        && (signupForm.email == signupForm.email2)
        // && (if countryRequired && signupForm.country.length > 0);
        // check signupForm.country.length IF countryRequired
