+tags: browser,beginner
+---
+
+Returns all the ancestors of an element from the document root to the given element.
+
+- Use a `Node.parentNode` and a `while` loop to move up the ancestor tree of the element.
+- Use `Array.prototype.unshift()` to add each new ancestor to the start of the array.
+
+```js
+const getAncestors = el => {
+  let ancestors = [];
+  while (el) {
+    ancestors.unshift(el);
+    el = el.parentNode;
+  }
+  return ancestors;
+};
+```
+
+```js
+getAncestors(document.querySelector('nav')); // [document, html, body, header, nav]
+```
