javascript get value of radio button not selected

Question

Perhaps a stupid question, perhaps because im a javascript rookie but lets say I have multiple groups of radio buttons with 2 or 3 radio buttons per group.

I can easily get rad1(if selected) by

if (radios[i].checked) {
            myradiovalue=radios[i].value
}

But now how will I get value of rad2 which is not clicked

Answer 1

if (!radios[i].checked) {
    myradiovalue=radios[i].value
}

Answer 2

Determine if the radio button's checked attribute is false and then set the value

if (radios[i].checked == false) {
    myradiovalue = radios[i].value
}
