Best way to find out if element is a descendant of another there is another question, very similiar to this one but its jquery.

so, how do I do it in js ?
I have divs a, b, c, d nested in this order.
also, not sure if matters, there is another a, b, c... and another. its not just a single element. there is many by same id/class.

so I want to see if d has a parent(no matter how deep it is nested, as long as there is some parent on top its ok) called a.

edit:
also, I had this idea that I could check childnodes of a and see if d is one of them, but couldnt implement it. if someone can get it working, itd be awesome.

// x is the element we are checking

while (x = x.parentNode) { 

    if (x.id == a) console.log(FOUND);

}
