Benchmark: Finding parent element: Closest vs Loop vs Recursion

HTML Preparation code:

<div class="parent">
  <div class="child">
    <div class="child">
      <div class="child child-last"></div>
    </div>
  </div>
</div>

Script Preparation code:


   
Benchmark.prototype.setup = function() {
  var isParent = function(el) {
    return el.classList.contains('parent');
  }

  var findParent = function(el) {
    if (isParent(el)) return el
    if (!el.parentNode) return false
    return findParent(el.parentNode)
  }
  var element = document.getElementsByClassName('child-last')[0];
};

Tests:

Closest
element = element.closest('.parent')
Loop
while (element) { if (isParent(element)) break; if (!element.parentNode) break; element = element.parentNode; }
Recursion
element = findParent(element)
