Walk up a DOM tree and return the matching element.

findInDomAncestry.js

const findInDomAncestry = predicate => node =>
    typeof node.nodeType === 'undefined' || node.nodeType === Node.DOCUMENT_NODE
    ? undefined
    : predicate(node)
    ? node
    : findInDomAncestry(predicate)(node.parentNode);

/*
 Example usage:
 
 const hasClass = cls => elm => elm.classList.contains(cls);
 document.addEventListener('click', e => {
   const target = findInDomAncestry(hasClass('foo-bar')(e.target);
 });
*/

Might be nice to abstract this further, to make it findInChain, where you provide the parent function.
That would make it usable outside a DOM context as well:

const getParentFn = node => node.parentNode;
const matchingParent = findInChain(matchFn, getParentFn, node);
