### insertBefore
|
|
|
|
Inserts an HTML string before the start of the specified element.
|
|
|
|
Use `el.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>
|
|
```
