unistunist utility to find nodes before another node.

Install

This package is ESM only: Node 12+ is needed to use it and it must be imported instead of required.
npm install unist-util-find-all-before

## Use

```js
import {u} from 'unist-builder'
import {findAllBefore} from 'unist-util-find-all-before'

var tree = u('tree', [
  u('leaf', 'leaf 1'),
  u('node', [u('leaf', 'leaf 2'), u('leaf', 'leaf 3')]),
  u('leaf', 'leaf 4'),
  u('node', [u('leaf', 'leaf 5')]),
  u('leaf', 'leaf 6'),
  u('void'),
  u('leaf', 'leaf 7')
])

var leaf6 = tree.children[4]

console.log(findAllBefore(tree, leaf6, 'leaf'))

Yields:

[
  { type: 'leaf', value: 'leaf 4' },
  { type: 'leaf', value: 'leaf 1' }
]
