+Inserts an HTML string before the start of the specified element.
+
+- Use `Element.insertAdjacentHTML()` with a position of `'beforebegin'` to parse `htmlString` and insert it before the start of `el`.
+
+```js
+const insertBefore = (el, htmlString) =>
+  el.insertAdjacentHTML('beforebegin', htmlString);
+```
+
+```js
+insertBefore(document.getElementById('myId'), '<p>before</p>');
+// <p>before</p> <div id="myId">...</div>
+```
