insert-before DOM element in a functional way.
npm install fd-insert-before --save
Let the DOM be like:
<div id="parentElement">
<span id="childElement">foo bar</span>
</div>```
```js
let insertBefore = require('fd-insert-before');
let sp1 = elem("span","meow")
,sp2 = document.getElementById("childElement")
,parentDiv = sp2.parentNode
insertBefore(parentDiv, sp1, sp2);
selectOne('#parentElement').children[0].innerText; // => 'meow'
insert-before :: parent -> newChild -> refChild
A curried function that takes in:
-
parent The parent of the newly inserted node.
-
newChild The node to insert.
-
refChild The node before which newChild is inserted.
