### insertAfter
Inserts an HTML string after the end of the specified element.
Use `el.insertAdjacentHTML()` with a position of `'afterend'` to parse `htmlString` and insert it after the end of `el`.
```js
const insertAfter = (el, htmlString) => el.insertAdjacentHTML('afterend', htmlString);
```
```js
insertAfter(document.getElementById('myId'), '<p>after</p>'); // <div id="myId">...</div> <p>after</p>
```
