+Runs the callback whenever the user clicks outside of the specified element.
+
+- Use `EventTarget.addEventListener()` to listen for `'click'` events.
+- Use `Node.contains()` to check if `Event.target` is a descendant of `element` and run `callback` if not.
+
+```js
+const onClickOutside = (element, callback) => {
+  document.addEventListener('click', e => {
+    if (!element.contains(e.target)) callback();
+  });
+};
+```
+
+```js
+onClickOutside('#my-element', () => console.log('Hello'));
+// Will log 'Hello' whenever the user clicks outside of #my-element
+```
